Leatherwood/Hi-Lux, Tac-Dot

IMG_20160803_173211305_HDR

Leatherwood/Hi-Lux makes a fantastic compact reflex sight that will compliment any firearm you need quick sight acquisition for. I had a perfect donor .22LR pistol a Colt Cadet semi-auto that sported an old out of date and bulky soup can red dot.

IMG_20160721_172004678

A quick glance will tell you what an improvement the Tac-Dot sight did for this handy pistol.

Let’s cover some product specifications before we head out to the range and burn some powder. The Tac-Dot measures less than 2.5 inches in length, and weighs 2.1 ounces.  The clamp type mount allows this sight to be secured on a picatinny rail or Weaver base. It’s waterproof so you can take it out in any weather and its shockproof construction can take any environment or recoil you can endure.  Sighting the Tac-Dot is quickly handled with friction windage and elevation screw adjustments that can be accessed by means of recessed screws.  A handy screwdriver is provided along with a precision dial wheel for fine tuning that tight group at the bench.  The 1x magnification eliminates parallax problems, plus there’s no need to focus, and the eye relief is unlimited allowing this sight to be used whether it’s mounted just 5 inches from the shooter’s eye or on a handgun held out 18 to 20 inches from the eye. The 4 MOA red dot reticle does not have to be centered in the lens when the firearm is sighted to hit where the dot is on the target…whether the dot is high…low…right…or left of center in the lens. The Tac-Dot sight features fully multi-coated optics for maximum light transmission. The brightness of the dot automatically adjusts to the brightness or dimness of the light. It comes with protective cover. Keeping the Tac-Dot Sight cover on while you are not using the Tac-Dot Sight saves the battery life.

 

Tac-Dot specs:

 

Power  1X

Object lens       21” x 16”

Exit Pupil Range            N/A

EYE Relief         Unlimited

Length  2.5″

Short Reticle    Dot

Elevation Adjustment  1 (MOA)

Short Feature   4 MOA Dot Size

FOV      49′

Coating             Fully Multi-Coated

 

Right out of the box I was impressed with the rugged design, light weight and speed of mounting. IMG_20160803_174709149 (1)

Everything you will need is packaged in the box. Once mounted a quick bore sighting and you are ready to put some lead down range. I really like the auto brightness of the dot no pushing buttons till you reach that perfect brightness. I’m afraid you’re aiming perfection  skill factor will diminish a little as you really don’t need to concentrate on perfect aiming with a reflex sight, just place that dot on target and squeeze the trigger! No more needing a perfectly centered dot in the objective lens, technology is awesome!

IMG_20160803_173304654_HDRIMG_20160803_173335978

The glass is extremely clear and the dot can be pushed right into a corner without distortion. No glare issue whatsoever when in bright sunlight and styling is sleek and effective. When a battery change is needed just loosen the allen screw lift the sight and replace with a CR2032, your still zeroed when reinstalled! That’s Leatherwood/Hi-Lux accuracy.

Comparing competitor pricing it’s hard to beat the value of the Tac-dot.

At the range only two sight adjustments had me punching X rings on the target then a switch to dumping rounds into a ballistic cube proved the zero was solid. Switching from heavy shade back to bright sunlight was easy with the auto brightness and I really like the light weight  this sight provides. Final thoughts on the Tac-Dot I really like it! well-built, light weight, easy operation and great features.

IMG_20160804_184021656_HDR

I just might put one of these sights on the 300 Black Out AR build I have on the bench. 45 degree back up sight to a Leatherwood CMR 1-4.

 

Until next time get out and burn some powder and  enjoy the outdoors.

Leatherwood PentaLux 4-20×50

One year ago to the day I posted about the Leatherwood PentaLux optics. Today I am writing about field testing the glass I mounted on a wildcat Mauser chambered in the hot 22-284 Winchester. After a routine scope mounting and bore sighting in the shop it was off to the range for zeroing and  some evaluation. The day was cool, around 37 degrees along with no wind.  I set up the bench bags that would give the rifle a solid rest.  Removing the bolt to compare bore centered on the target with optic center of the reticle proved right on target at 50 yards. 20 fresh rounds loaded up with 75 grain A-Max bullets are charged with H1000 powder, a proven 1/4 moa load.  You see the rifle will be used to test the accuracy of the optics.  Ocular adjustment was easy with a few turns giving way to a crisp clear glass etched reticle.  Then on to dialing in the focus of the target which is made very convenient via a side focus knob. Slipping a round on the benchrest follower allows the bolt to lock up a snug chambering then a light touch to the 6oz Jard trigger ignites the fun. Low and left is where the bullet printed. I adjusted  just a few clicks up and right and had the second shot dead center.  Clicks felt good and positive although seemingly quiet (I couldn’t hear a freight train going thru a nitroglycerin plant ….thanks Clark). Two shots fired and we are ready to go to the 100 yard target.  After dialing in a clear target at 100 yards the focus knob read 100!  That’s factory calibration for ya!

100_3323

So far things are going good at the bench.  Another round is chambered then fired out to the 100 yard mark. This time all that is needed to center the shot was one click left of windage and with the .01 mill adjustments pin point accuracy is easy. I was pleased with three zeroing shots allowing the fourth shot to drill dead center at the 100 yard mark!

100_3329

Another feature of the PentaLux is an illuminated reticle.  I ordered green illumination and the rheostat has two off positions 180 degrees apart on the dial.  This optic is built with a 30mm main tube, fast eye focus, zero re-settable turrents (no zero stop) and side parallax adjustment (a Leatherwood first). For a five times magnification (4-20 tested) scope it has a compact profile and the 50mm objective lets in plenty of light.  I hope Leatherwood/Hi-Lux will offer a sunshade for the PentaLux line as I am fond of using them.

IMAG1194_1

Turrent covers protect the adjustments from accidental moving when handling and moving thru the woods, while looking for that shot opportunity at your game. A handy throw lever is screwed to the power ring for quick positive dialing magnification.

100_3324

The reticle is calibrated in mil’s and moa with ranging scales to size up targets at distance. Clicks are in .01 mil’s (.036″@ 100 yards) as opposed to moa clicks (1″ @ 100 yards). You have probably noticed the bright blue elevation turrent in the pictures.  This is a modification I made to allow quick zero settings at various ranges. After turning down the knurled edge on the turrent, providing a smooth round surface, I ordered a custom ballistic tape from http://www.customturrentsystems.com (post 5/20/2015).  The tape is calibrated for the 22-284 Winchester round with meter marks from 100m to 1ooom.  Ballistic load data is printed around the top edge and click marks circle the bottom edge.  The tape is created from a vast choice of colors and fonts along with character sizing.

100_3326100_3322100_3320

The PentaLux is a well built scope with features that are easy to use (side parallax, power throw knob, fast eye focus) and as always, the erector tube stabilizer. I sent 20 rounds down range that day without a hint of zero shift!  I sent a 75 grain A-max bullet down range at 20 power only to have the second shot enlarge the same hole slightly.  After cranking the power ring back and forth several times ending up back at 20 power.

In conclusion, I like the PentaLux in 4-20×50!  Sure, it could use a sunshade and I modified the elevation turrent for my ballistic load, however, it is well built, holds zero and crystal clear with sharp focus. Check one out on your favorite rifle.  Just be forewarned……you’ll likely buy other Leatherwood/Hi-Lux optics.

 

 

Until next time, burn some powder and enjoy some trigger time

January Shot Show in Vegas, Guns Guns and Guns

Wow things have been a blur since November I finally have time to think about all the stuff that happened. After a good marinate venison back strap meal finished off with a good strong espresso I can reflect on the amazing gathering in Las Vegas “The Shot Show”! this was my first time at both the show and Vegas.

IMAG1134_1

With mild weather in the 60’s I was delighted to be out of the low 20’s and snow. Palm trees, Elvis, Elvis and more Elvis wherever I looked, first off a tour of Hoover Dam was in order my wife Kerri and I took the 8 hour tour that included stops at typical tourist sites and lunch at you guessed it a casino. Yes we saw the whole Dam thing (I was tiring of dam jokes too) anyway it’s quite amazing how it was build and our tour started 720′ below grade.

IMAG1145 IMAG1143

With massive turbine generators and spotless clean facilities this site not only provides power but also water to vast desert areas.  After the tour we found a good local place to eat called Ellis Island Casino and enjoyed ice-cold craft beer and great tasting burgers. The next morning started off early with a shuttle ride to the Sands Expo Center  then taking in as much of the 2000+ exhibitors as I could, with 64000 attendees you can about imagine what a sea of people flowed thru isles of vendor booths and yes you can touch, feel, twist knobs and pull the trigger on anything there! A 1911 45ACP dual pistol machined as one ( two barrels one trigger,hammer,slide and darn massive to hold on to) then how about a back pack 50 caliber bull pup rifle! 30″ long, kicks like a 12 gauge and effective to one mile, all this weighing in at 30Lbs

IMAG1165 IMAG1164

Stopping by the Leatherwood Hi-Lux booth was a great time as I met Corbett Leatherwood  and looked over some very nice proto type first focal plane optics that will be available soon. Just before leaving for Vegas I received my PentaLux 4-20×50 scope and since then have mounted it on a 22-284 Wildcat Mauser varmint rifle

IMAG1194_1

This is a view of the new proto type first focal plane Tac V scope

IMAG1158 IMAG1157

Another stop was at the Wolf ammo booth since this shoots so good in the Mosin Nagant I have and a  good source of ammo is always a wise investment wolf-ammo-catalog_600

20151130_142103_001 Looking down the business end of a Nagant that loves to digest wolf Ammo 20151130_141949 Another interesting stop was at the Bluegrass Gun Stocks table, this Nagant is resting in a Special Forces Tactical maple stock with a Rock Solid Industries scope mount and yes a Hi-Lux Uni-Dial 4-16×50 optic. Other exciting stops included the Weatherby 6.5×300 Magnum Accumark rifles and how about a 100 round dual drum magazine for your AR15 weatherby-revamps-mark-v IMAG1229 IMAG1227 IMAG1223_1

I sure enjoyed meeting so many people at the show and connecting with potential business deals. I hope to spend some time at the range testing the PentaLux optic and writing a first hand review.

New rifle, New optics, New 06 load, New favorite

Another November deer hunting season is here with cold weather, no snow to start with and a new rifle along with  30.06 loads to test. I mounted a Leatherwood ART 2.5-10×44 scope to on a Remington model 783 chambered in the classic 30.06 round. Northern Michigan white tail deer are an exciting game animal to hunt and require time in the woods to pattern them. I took some photos of the trees we sit in showing the tight shooting opportunities for taking a Michigan white tail.

100_3257    This stand is for south west winds       100_3258

100_3266  This stand is for north east winds        100_3267

 

The Remington 783 is very light with a 24″ barrel and composit stock this rifle was accurate right out of the box, during range evaluation. I shot some 30.06 M1 Garand nation match 168 grain ammo and was suprised at how well it grouped. With some load work and a switch to IMR 4064 this Remington 783 came alive and started drilling rounds down range! Five shots in one ragged hole now thats better. I mounted a Leatherwood ART scope that will dial down to 2.5 power for these tight shots allowing a big field of view for locating game. One mention about the cross fire trigger on the 783 is that it feels very crisp, breaks like a glass rod and is adjustable down to 2.5LB of pull.

100_3260    100_3268

 

Before the season I worked up a load suggested by a forum member on http://www.longrangehunting.com.  I have never found a load to group so good in two different rifles ( one a Winchester mod. 70 and this Remington 783)

** THIS LOAD IS SAFE IN THIS RIFLE** REDUCE POWDER CHARGE BY 10% AND WORK UP SLOWLY OBSERVING PRESSURE SIGNS**

IMAG1024   This is a five shot group  at 100 yards with 150 grain sierra pro hunter bullet sitting on top of 51.2 grains of IMR 4064, ignited with CCI BR2 primers.

I have reviewed  the optics and rifle in past blogs so I wont rehash the topic, however this rifle is chambered in 30.06 and with an estimated 3000fps load this 150 grain pro hunter bullet should nail a Michigan white tail “DRT”    ( dead right there).

 

This doe was taken with the 783 on a cold morning and the recovered bullet shows excellent expansion dumping all the energy into the deer dropping it right in her tracks.

IMAG1067  IMAG1075 Two different photos showing bullet blow up IMAG1074

 

 

With cold weather and snow falling down during an early morning hunts the warm cottage and hot lunch was an inviting break. Thawing out the rifles and ourselves became a daily routine.

20151121_113305  Rifles hunted with were a 6.5 Grendle AR15 platform and the Remington 783 in 30.06 IMAG1070

 

If you are looking for a economical rifle that functions flawlessly along with an excellent trigger the Remington 783 is a great deal. Accuracy was sub MOA with both the .243 and 30.06 I tested, along with fantastic Leatherwood HI-Lux optics ( 4-16×50 uni-dial & 2.5-10×44 ART ). This hunting package is hard to beat and inviting since you don’t need to invest $900 to build it.

 

100_3262  IMAG1024  100_3265

 

 

I hope you filled your tags with venison this season and had a very Happy Thanksgiving sharing good times with friends and family.

 

Until next month get outdoors and burn some powder!

Mosin Nagant and Long Sleeves

 

 

More years ago than I care to remember I had worked on a rifle for my Uncle Gale, he took me on my first Canada fishing trip then again my first Northern Quebec Caribou hunt those are great memories and awesome northern lights too.  The rifle  was a Mosin Nagant that was to be sportorized  Nagants are not the sleekest looking rifles I thought to myself back then along with the chambering in 7.62x54R which is not to popular. He mentioned that he wanted something unique, not something everyone has so I did the work he requested and delivered a sporter Nagant to him. Funny that ever since then I have kept an eye on those particular rifles watching prices go up and down along with surplus availability, I don’t know why it just seems recently I thought that it would be unique to build a Tactical Mosin Nagant (yes I said unique). I found a web site (www.socamo) was running a TV channel on ROKU TV (the mosin nagant channel)  I watched several shows and thought Wow these rifles are really accurate.

 

IMAG0909_zpsyqb0nxj6Russian Mosin Nagant 91/30 chambered in 7.62x54R

 

I found myself picking up a Century Arms International Russian 91/30 rebuild with a 28” barrel and a very nice looking bore! Most available 7.62x54R ammo will have bullets measuring .311” and this barrel slugged at .312” so reloads looked to be in order. Inspecting the rifle parts revealed components to be in excellent shape and I started removing the sights from the barrel. Rock Solid Industries (www.rocksolidind.com) and Blue Grass Gun Works (www.bg-gunstocks.com) have some very nice custom parts for building Tactical Nagants and after talking with them I ordered the needed items. A threaded Tactical handle along with a knurled bolt knob finished off the bolt body and the holes needed to be drilled and tapped on the receiver for the Weaver scope base (beefy 10-24 bolts are a nice touch). I polished and blued the receiver to a nice high gloss finish along with polishing up all related bolt components, this allows for a smooth working bolt.

 

100_3144 components of a build.

 

There are several little tricks to smoothing out a Mosin Nagant action and bolt for super smooth operation and bolt preparation is at the top of the list! Fit, polish, and lubrication along with slightly lightening the firing pin spring will reveal tremendous benefits with feel and function. With not removing the original barrel I chose not to do any bolt lug work as not wanting to alter headspace with the 7.62x54R round. The stock I ordered was a Special Force Tactical in Maple it’s loaded with nice features including swivel studs, aluminum pillars, and adjustable cheek piece all this along with a soft rubber recoil pad round out a super nice looking stock.

Once the stock arrived glass bedding was in order, I always add an extra recoil lug bedded into the stock just behind the front receiver lug recess. I think this added support helps keep the receiver from any rearward movement from recoil and along with pillars and full stock bedding things just don’t move! Timney supplied the trigger (www.timneytriggers.com) and is the only aftermarket adjustable trigger that has great reviews so yep I put one in. Adjusting down to 1.5 pounds of pull was easy and no slam fires happened during testing, adding an aluminum trigger shoe helps dress up the looks along with providing a wider pressure point for your finger tip.

With the receiver and bolt work done I focused my attention to the barrel, I didn’t like the small diameter and pencil looking barrel however I didn’t want to invest in a new barrel either. Looking back in my American Gunsmith Association publications I found an article by “Norman Johnson”  Barrel Sleeving A New Way, October, 2012 .   I like to experiment with different things when working with guns and the concept of sleeving a barrel to improve accuracy and dull vibration harmonics really interested me. I researched other theories on the barrel sleeves along with types of compounds to fill the void between the barrel and outer sleeve, nodes of vibration and barrel whip are all very interesting subjects. One interesting fact was the need to displace heat generated during firing the bullet thru the barrel along with the ability of the compound to withstand the shock of recoil. While digging thru data I found a company the does exactly what I was planning to do, The Straight Jacket is the name of the product and with the price being more than I wanted to expend I ordered up some material from a local supplier and headed out to the shop for some machining time. I have an old Atlas Laith that I use, no cnc programming no electric beds just good ole fashion 1930’s dials and pulleys. There’s something nostalgic about building parts off these old machines that I really enjoy.

 

100_3203 epoxy bedding.

100_3178 military barrel along with 1-1/4″ stainless sleeve.

 

The Mosin Nagant project really took a turn at this stage of the build, I had ordered a 1-1/4” stainless steel tube and cut it down to 28” long, that will cover the entire military barrel that now sports a newly cut 11 degree target crown I had just cut. Turning to a depth of 3” the inside diameter of the sleeve to .003” under the barrel outside breech measurement will provide a nice tight press fit. Along with the sleeve I made a muzzle cap to fit around the barrel muzzle and inside the sleeve to finish off the muzzle end. An important note here is metal coating to prevent corrosion from the heat displacing compound, the barrel must be properly coated to protect it from any form of weakening. After an epoxy coating process and mixing up a batch of special formulated adhesive the sleeve was pressed on, bore plugged and then filling of the empty cavity. Once cured the sleeve is solidly attached to the barrel and ready to assemble to a complete rifle. A finished Tactical Mosin Nagant wearing a blonde maple stock looked very nice with the 28” long stainless barrel, now to see if the labors will pay off at the range.

 

100_3181barrel filled with compound and muzzle cap installed, letting things cure.

 

Once out to the range with a newly built rifle and some factory ammo I am thinking if this rig will print 1” groups at 100 yards I’ll be fine with that. I can always load up some rounds to try and tighten up the groups, the sun was gleaming thru the leaves with temps in the upper 50’s a 25+ mph wind was blowing across the bench keeping things interesting.  A quick check at 50 yards easily zeroed the Leatherwood Uni-Dial 4-16×50 scope then out to 100 yards to set the initial zero, 148 grain bi-metal jacket Wolf “white box ammo” started the range day and 100 yard results had groups printing around 1-1/4”. Not to impressed with the accuracy would be an understatement although I did note that the barrel was not very hot after several rounds cooked thru the bore. Switching to the same type of ammo in Wolf’s “Black/Red” box really turned the day around! The first three rounds made a nice crescent ½” group, this is a freak thing I thought judging from previous rounds fired. Timing the shots again I touched off three more rounds and watched as they made one ragged hole at the bull’s eye, that’s more like it the blonde Russian Mosin Nagant started to really settle in and drive some impressive groups with Wolf ammo. Steel case, bi-metal jacket bullets and all at economical prices that shoot darn good. What’s not to like about that!   When someone mentions  what are you going to do with that old beat up gun, just smile and start putting on the Long Sleeves!

100_3232100_3218 that’s more like it sub-moa @ 100 yards!

 

 

I have some really great news about the Remington 783 chambered in 30.06 along with the Leatherwood ART 2.5-10×44 scope I mounted on it. I’ll fill you in after deer camp. Until then get out there and enjoy the outdoors with your favorite rifle.

October, coffee pumpkin pie and the smell of burnt powder.

October is here a cool breeze across your face, that crisp air allows the crack of a wildcat cartridge to  echo as you watch a super sonic bullet hit it’s mark with a rewarding whalip!   Once again fall has arrived and it’s time to check zero on the rifles you intend to heat up the barrels on. There is something  special about a cool fall day and the smell of burnt powder, I pulled an old favorite varmint rig out for a day of trigger therapy and reminiscing just how much I missed shooting the 6mm-284 Winchester. Looking thru my load data log book I found the ammo batch that closest suited the days temperature, with 66grain match hollow point bullets and a large dose of Reloader 17 powder I was all set for touching off the Jard 6 ounce trigger. It’s nice to know you can set quarter sized targets out at 100 yards to verify your zero when you trust the optics you use. A touch of the trigger sent the first round down the 12 twist bore at just under 4000 fps down range to hit a bit high of the X ring, this was true for the second and third rounds too and then my eagerness got the best of me and round four landed low and right opening the group to a big ol  5/8″. Many more rounds were sent down range that day and dime sized groups were ok  as I began to remember just how to coax the true potential out of the ol girl, a Mauser GEW 98 with a glass smooth bolt feel and a very heavy laminated  stock made for a pleasant time of burning powder. I took some pictures after cleaning the bore and wiping down the metal to ward off any possibility of rust from handling, I hope this taste of a cool fall day has you grabbing an old favorite and heating up the barrel remembering just how much fun these time pieces are. Now where is that slice of pumpkin pie to go with my coffee.

Feed your Mauser a Swift diet

This month I am writing about a tech topic relating to custom work when a specific cartridge is used. This project is within the ability of anyone with access to minimal tools and a welder.

 

Feed your Mauser a Swift diet

Mauser rifles have a certain attraction to be built into various chambering’s you can find them most anywhere learking around gun shops hiding at gun shows and even forgotten in a gun safe. Some feed without issue while others drive the owner’s nuts with shorter/smaller diameter cartridges. This article will cover just such an issue, I was working on a M98 Mauser chambered in the iconic 220 Swift.

You may wonder why someone would re-barrel a M98 Mauser action to a shorter, smaller diameter cartridge and have feeding and chamber jam issues while striping a fresh round from the magazine. This rifle in particular was a Large Ring M98 Mauser military action with a fresh 220 Swift barrel, when the magazine was loaded with rounds the bolt would push the rounds back and forth while manipulating the bolt. An overly large magazine space for the smaller 220 Swift cartridge would cause the cartridges to become jammed in the magazine as some cartridges would be pushed extreme forward while others would be pulled reward with the top cartridge occasionally popping up out of the feed rails. This is a common issue when the magazine is sized for a 30.06 sized cartridge, some of you may be thinking why not buy a short cartridge follower conversion kit? Yes that would be an option however I wanted this rifle to feed and chamber a 220 Swift round smoothly every time. With various countries manufacturing Mauser actions and with minor fluctuation in tolerances there would be no way to be certain a conversion kit would be a drop in fix.
On the bench I would load a dummy cartridge in the magazine and observe how it feed as it was stripped from the follower. As the cartridge was pushed forward there was not enough upward angle to position it for a smooth entry into the chamber, what I needed to do was angle the follower to help point the cartridge into the chamber. With the follower removed I filed a tapper angle to the left side top rail of the follower top that contacts the receiver left feed rail. The follower measured .368” on the back edge and .300” on the front edge, I removed .168” of metal from the front edge while tapering an edge to the rear of the follower. This was enough to start the cartridge in a good angle for chambering while pushing the bolt forward. This worked good for single round feeding however I wanted to fill the magazine and continue to strip and feed rounds smoothly. I needed to determine what length to cut the follower to, this 220 Swift barrel had a 1-12 twist and 55 grain bullets would be the heaviest loads used. I measured factory cartridges with 50 & 55 grain bullets loaded in them and settled on an average cartridge overall length of 2.600” allowing some extra space to prevent jammed cartridges in the magazine. This measurement would determine that I needed to cut 10mm off the follower to make a full length cartridge bed for the modified follower.
The cut was made slightly ahead of the back edge of the follower as I would weld the back piece back on, once welded back together then with some filing, shaping and polishing the now shortened follower fit the desired cartridge length perect.

The magazine well will need a block to fill the gap created by modifying the “shortened follower”. I used a piece of black nylon with rough measurements of 45mm x 17mm x21mm, since all Mauser’s have slight differences in trigger bottom metal you will need to hand fit the block to the individual metal. With a belt sander small amounts of material can be taken off while test fitting the block, it’s ok to make the block fit the sides of the magazine snug however the block should allow the follower to move freely through full travel without any binding. A final smooth polish to the follower cartridge face side of the block will ensure cartridges slide freely against it.
The block will need to be cut to correct length to allow a snug fit from the receiver inner feed rail stop to the removable bottom metal, work slow and test fit often for a perfect fit. Next up on the block fitting will be opening up space for the bolt to pass over it while still keeping the cartridge held forward while lying in the follower. A dermal tool with a drum sander will make quick work of this task, again trial fit and remove small amounts of material at a time. Once fit the bolt should not bind anywhere as it passes over the magazine block while also having the cartridge head stop against it. With the block and follower made a correct size magazine spring will need to be selected, I have quite a pile of left over magazine springs to dig thru hoping to find a favorable donor (another reason to keep old gun parts). A magazine spring is selected by measuring the space from the front side of the new block to the front inner side of the magazine well. With the spring compressed the center leaf length needs to fit in the magazine space with plenty of free movement. The leaf that fits into the follower spring clip will need to be shortened and have the narrow side section filed back to allow full engagement into the follower groove while allowing the rear portion to be held against the follower stop.
Test fit the spring by pushing the assembled spring and follower down into the magazine. When binding is noticed the cure is to shorten the leaf spring that fits into the floorplate. When this spring section is shortened it allows the magazine spring to pivot the follower forward allowing free travel thru the magazine. Now you should have smooth feeding cartridges when fully loaded into the magazine along with a good feeling push feed when stripping a fresh round.

Modifying the follower and associated parts to accommodate a smaller cartridge will improve the overall function to strip and feed rounds smoothly. Attention to small details like this will make customers return for other work and the complements spread by word of mouth are the best P.R. you will ever receive!

Leatherwood ART II 2.5-10X44

It’s the end of August and time to start thinking about the condition of your optics again. Soon the ranges will be filled with hunters sighting in their rifles and struggling to find that sweet point of impact spot for effective down range hits without thinking about sight adjustments. What if you had a scope that would range a target, adjust elevation (bullet drop) and adjust magnification all in one motion.

Help is on the way from a company located in sunny California “Leatherwood/ Hi-Lux”. You have read other blog posts I have on the Uni-Dial scope from this same manufacture, unlike the Uni-Dial that needs individual flags to be set for elevation settings to calibrate a specific cartridge. The ART II series scope will auto adjust elevation and magnification with an interlocking cam system specific to Leatherwood.  Versatility of application on various rifles is where this ART II scope stands out with a built in weaver rail mount that is at home on a M4 flat top or a Model 70 Winchester. With a line of sight that measures 2.5″ above the bore it is a bit high for a bolt action (nothing a cheek pad won’t fix) however it is perfect for looking thru a A2 front sight on any AR15 style rifle. For some scope specifics there is a reticule stabilizer, glass etched no-math mil dot reticule, 1/4 minute click turrents (zero stop adjustable) and crystal clear 44mm objective glass.

The above photo shows the magnification ring attached to the range ring. Viewed from the rear the lower number is scope power and the top number is yardage to a target, note this set-up has you zeroed at 250meters ( aprox. 247 yards). As you turn the dial counterclockwise wise the magnification is increased proportional to the yardage ( in meters) all the way out to 1000meters! Once you determine the cartridge to be used and ballistics are known the manual will provide a calibration number to set the range ring to, this calibration sets down range ballistic drop for your cartridge, no clicking turrents or counting mil dots using mental gymnastics that would have you guiding a cruse missile. If you would like more magnification at  any given range you can simply disengage the magnification ring from the range ring and crank up the power, notice the small thumb screw ahead of the cam ring ( it’s a locking range ring set screw to lock in a range while dialing thru several magnification settings) I never noticed a need for it however it available to lock down if needed.

Mounted on a M4 flat top the optics are set perfect to sight over an A2 front sight. If you have never looked thru a Leatherwood/Hi-Lux optic you owe it to yourself to do so. Read some reviews and decide for yourself but don’t discredit this manufacture before sending some lead down range and seeing how well they are build.

Until next month get out there and put some lead down range.

Proposed changes to “ITAR”

Proposed changes to ITAR

The State Department is considering revising the International Traffic in Arms Regulations, called “ITAR”. To read the notice in the June 3 Federal Register   (http://www.gpo.gov/fdsys/pkg/FR-2015-06-03/pdf/2015-12844.pdf)     announcing their intentions. What this means is they could make it illegal to post or publish any technical data about firearms in the public domain without first getting government permission. This could have a huge negative impact on your favorite gun blogs, websites, forums, magazines, YouTube channels, or any other public domain. Any information relating to firearms/guns would need to have permission from the government before publishing any technical data.

This looks like another anti-gun attempt to revamp the rules and regulations without involvement of Congress. Why should you be concerned? Well you are reading this blog and if passed this site and many related sites would be gone, banned unable to post without government permission. There is something you can do, you can post a public comment until August, 3, 2015 protesting this change. A large enough public outcry stopped the ban on M855 .223 ammo, it can stop this to!

Follow this link to the proposal page and you can post a public comment along with other fellow 2nd amendment right believers.

“ITAR” accepting public comments (http://www.regulations.gov/#!documentDetail;D=DOS-2015-0023-0001)

Below is my public post that I submitted and I encourage you to stand firm and fight for your rights.

“I strongly oppose the recommended changes to  “ITAR Amendment—Revisions to Definitions; Data Transmission and Storage.” As this would put a vast majority of UNITED STATES AMERICAN CITIZENS in violation and subject to prosecution just by posting information on a blog, forum, ect… electronic site. Will the freedom of information act be the next item on your agenda? This will greatly impact the federal revenue (TAXES) you so greatly need as suppliers, manufactures, hobbyist, gun writers, magazine articles, the list go on and on will not be able to interact in a free manner on your so called restricted topics. This will have an impact on purchases of accessories, new innovative products and manufactures of sporting arms (also optics, ammo, gun cases) not being able to advertise products without government approval, I don’t believe that is free enterprise.

Restriction and or removing this type of information from access to UNITED STATES AMERICAN CITIZENS will impact firearms schools training technicians, engineers and developers. Will printed hard copies of books and magazines be next?

The First and Second amendments are still the law and still our rights! Not to be infringed upon! This country was built on fighting for our freedoms, the UNITED STATES are just that UNITED let’s keep it that way. Information is knowledge and knowledge is only advanced by accessing information, locking up the internet based firearm related information is not acceptable by me or other UNITED STATES AMERICAN CITIZENS.”

Scopes and more scopes, how to decide what works best.

Now that summer is here, yard work is under control and all those graduation open house food fests are done. It’s time to look over your varmint/target/hunting rig and decide if an optic up date is in order. Manufacturing improvements are providing better more affordable glass for the shooting public along with some features that would otherwise only be available on high end glass.

IMAG0846

 

30mm main tubes are all the rage today with some even providing 34mm -40mm main tubes (Burris & Valdada). One myth about main tube diameter is the ability to allow more light for dusk /dawn  applications, the ability to allow more light in is the function of the objective lens ( forward end of scope) one example would be a 50mm bell. The above photo shows a 50mm bell (top scope), 44mm bell (bottom scope) and a 28mm CQB  bell (middle short scope), all will do a good job for there intended purpose with the 50mm getting the nod for allowing the most light in. I personally go with 50mm bells and 30mm main tubes as they are bright enough for those dark gray Michigan days and early evening shooting.

Other nice features would be side paralux adjustment knobs (only really needed above 10X). Leatherwood Hi-Lux has a unique 45 degree angle paralux knob however the new PentaLux sports a left hand side knob (Industry typical). While we are talking adjustment knobs do you remember the “Burris Posi-Loc” ? before Burris marketed that feature the bench rest community used a “Tucker conversion reticule lock” the purpose is to provide added erector tube support to stabilize the zero position of click adjustments (making the scope more repeatable for consistent shot placement). These tension buttons are typicaly located on the bottom left side of the turrent housing, you can see the one I made and installed on the BSA 36X target scope and yes it works fantastic!

100_3021

 

 

Zach 200yrd -1 The Weaver 24X T series scopes have 4 internal points of erector tube stabilization built in already. A fantastic scope for the money.

 

The 30mm main tube allows more elevation and windage adjustment than a 1″ main tube would, this will come in handy when you are cranking thru clicks to make that long shot elevation adjustment. Re-settable zero adjustments are a nice feature (most scopes have this) but what you need to look for is a zero stop feature, this will allow you to set your desired zero and after a days shooting and clicking thru  turrent adjustments you can simply turn all the way down to the stop and you are at your preset zero.

Reticule choices are abundant so look thru several models to decide what works best for you, weather it be a fine cross hair dot for pin point shots at that pesky crow or a Mil dot system used for hold off points. Most are glass etched and illumination features are common, first focal plane scopes will magnify the target and reticule image at the same rate allowing for Mil dot adjustments at any power. Second focal plane scopes will grow the target in relationship to the reticule staying the same, this set up needs to be at 10x for Mil dot estimation so make your adjustment and crank up the magnification.

Turrent click need to be tight and crisp, try out some different models and you will feel the difference! mushy and sloppy are not conductive to accurate point of impact movement. Hunting set up rigs most likely are zeroed and left alone so clicking thru 30 minutes of angle will not be an issue there, once again what’s your intended use will determine the optic you need.

IMAG0843_1

One last thing I will mention is to keep the lens covers closed when not using the scope in bright sunlight. As light enters thru the lens it magnifies the internal heat inside the scope this will dry out the seals and flake the interior coating. Just like when you burnt that ant on the sidewalk with a magnifying glass when you were in elementary school….Ok so maybe it was just me that did that:/

 

Get out to the range and burn some powder while testing out your new optics, shoot the box to check clicks, and check for impact shift while dialing magnification.

 

Until next month spend some time behind that trigger. Right on Dead on All the Time
