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.

IMAG0999_1

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.

 

IMAG0994_1

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

AMMO WANTED

Ammo Wanted
The title says it all “Ammo Wanted” whether it be 22LR, 223 rem (or Nato what ever your flavor), 22-250 or even hotter 220 swift! Store shelves are somewhat stocking up at exorbitant prices and that fun-loving plinking round that just seems to be more valuable than gold, yes the 22 long rifle.
If you are trying to cope with the pulsating shortages and infrequent supplies to be hoarded, you have already noticed brass, primers, powder and bullets at a scarcity. I reload most everything I shoot and that includes a tiny 25acp! talk about a test of finger dexterity and at 1.3 grains of powder per reloaded round a pound of powder will last a life time. Bring the 300 Weatherby Magnum to the bench and that monster wants 80 grains of a particular powder per reload. Now the powder is going fast so where do you go to purchase components and loaded ammo affordably? You could drive around to local gun shops checking daily for inventory drinking up that fuel at $2.60 a gallon ( for today).
I found a web site search engine that will look everywhere for current in stock availability in “real time”. Weather it be Cor-Bon ammo, Underwood Ammo, or bulk surplus corrosive if you choose they are all listed. So grab a beverage (non alcoholic since you are dealing with ammunition) and check out this link.

I’ll post more when I find the sites that are trusted and not scams (like “Personal Choice Outfitters” major scan site)

Leatherwood Hi-Lux Optics PentaLux scopes

 

Hi-Lux TAC-V 4-20X50 SF IR (3)

 

 

 

Leatherwood Hi-Lux Optics PentaLux scopes

 

With the 2015 Shot Show behind us now I was excited to hear Leatherwood/Hi-Lux is offering a new 5X zoom optics line. The PentaLux TAC-V scopes are based on a “Five Ratio” magnification range offered in 2-10x42mm and 4-20x50mm models.  Build with a second focal plane illuminated reticule, 30mm one-piece tube and designed for the serious long range shooter. With a price close to half of what you would pay for other 5x zoom capable optics this Leatherwood offering is sure to be noticed among the shooting community!  One interesting factor is with the 5x zoom (2-10 & 4-20) these scopes are shorter than other comparable 5x zoom scope.

 

TAC-V models offer MIL adjustment each click with either the windage or elevation turret moves bullet impact .01 mil. @ 100 meters.  TAC-V models will have an all new illuminated etched glass reticle with ranging scales and hold-over aiming marks in both MRAD and MOA.  The side parallax/focus adjustment is moved back and to the left side following suit with other optics manufactures (the 45 degree adjustment knob is unique to Leatherwood/Hi-Lux).

I have noticed point of impact drift while dialing power range with other brand scopes, you won’t find that issue with a Leatherwood! They just plain out hold zero.

6.5×55 Ackley Improved 1/4 minute Mauser

6.5×55 Ackley Improved     ¼ minute Mauser

 

Selecting an action and chambering for a new varmint build is always rewarding.  You learn more about the cartridge of choice while deciding which one fits the current need. I have been shooting 6.5s for years and figured the Swede 6.5×55 cartridge would need a second look.  The challenge would be to rechamber a standard military action “ a 1903 Swedish Small Ring M96 Mauser “, with a listed breech pressure from 45000 psi to 66000 psi (Bolt Action Rifles 4th edition by Frank de Haas & DR. Wayne van Zwoll). An Ackley Improved case looked like a excellent option.  With all variables kept the same i.e. barrel length, twist rate, and bullet weight, a minimum 6% gain in velocity would qualify for an Ackley project. The blown out Ackley brass is capable of a 13.7% gain in velocity over the standard cartridge, with a listed velocity of 2900 fps using a 140 grain bullet it is a vast improvement over the standard 2550 fps. I chose to chamber the little Swede in 6.5×55 A.I. 40 degree shoulder also known as 6.5×55 BJAI   “Bob Jourdan Ackley Improved“, another factor that favored the  Swede build was that the bolt has gas vents ( a safety factor for a ruptured case or primer )

 

The build began with updating, squaring and sporterizing of the military action: forging bolt handle, tang contouring, polishing feed rails, lapping lugs, receiver squaring  and chasing receiver ring threads, drilling / tapping for scope mounts.  A #4 contour ( 1.125” dia. ) 4140 steel bull barrel was ordered from E.R. Shaw and since this was a nonstock chambering I needed to ship them the necessary tooling to short chamber this hopeful tack driver. My next call would be to Richards Micro-Fit Stocks in California for a Carlo Walnut Straight Line Thumbhole stock, I made good use of my time while waiting for the barrel and stock to arrive by fine tuning the trigger guard.  The trigger bow was reduced in width and tapered to reveal a sleek appearance, it is inspiring to see with each pass of the end mill cutter that the military aspect of the Swede grew more distant and a contrasting sleek look became clearer. The bolt was jeweled and bolt cocking piece laith turned and tapered then fit with a Beuler low safety. All metal parts were bead blasted and blued with the bottom metal floor plate embellished with a hopeful logo “SUB-MOA“. After some searching a low pull weight target trigger was a difficult item to find. A call to Huber Concepts revealed that minor sear modifications to the M96 Swede would allow me to install a Mauser M98 Match Grade Trigger with a 27oz pull weight. The people at Huber Concepts really know their triggers, are very friendly and willing to offer any help with your current needs.

 

Once the barrel arrived I fit and headspaced it to the action. The Richards stock was shaped, bed and given a gloss hand rubbed finish. I use High Score Pro Bed 2000 to bed the action from the rear tang to 1.5” in front of the receiver ring; this gives support to the bull barrel while still allowing it to be free floated. A complete bedding of the trigger guard metal has proven very effective on previous Mauser actions I have built so I stick with this method. Topping off everything were Redfield rings and base with a BSA Platinum 24×44 A/O scope. Redding dies would be needed to reload the 300 rounds of new Speer 6.5×55 brass after fire forming. After reading pages upon pages from reloading manuals and consulting on-line information regarding types of powder and burn rates the 6.5 Ackley likes. I decided to start development with IMR 4895 for fire forming and IMR 4831 for newly formed cases, yes I know 4831 has a slow burn rate and I was told to use a faster one, however I discovered many 1000 yard shooters referring to how the 6.5×55 Ackley always seems to like 4831 very very well. Referring to P.O. Ackleys book “handbook for shooters and reloaders“ and www.imr.com starting loads were developed. Cases were prepped by deburing the flash holes, annealing the neck and shoulders and neck sized.

 

A charge of 42.5 grains of IMR 4895 powder was ignited by CCI Benchrest primers pushing the Sierra 85 grain Varminter H.P. bullet out of the 1-9 twist tube at a velocity of 2900+ fps. I had decided to polish the chamber to a near mirror finish after researching the topic regarding case/chamber grip, the results proved to be quite pleasing with very smooth extraction and no gas bleeding past the cartridge. The newly fire formed brass reviled a crisp shoulder angle and perfect case form with no high pressure indicators. To my surprise after bullet seat depth was adjusted deeper to 2.756” cartridge O.A.L. the 85 grain bullets printed quite well out at 100 yards. This proved to me that “SUB-MOA” was well with in sight as a 3 shot group measured 0.122” center to center! A further adjustment of the bullet seating depth was made; I went .014” deeper to obtain an O.A.L. of 2.742”. Range results proved that occasional bug holes were the norm. so the previous 2.756” would stay. I had good intentions of trying different powders during fire forming but its rare that the first load development works so well. With an accurate load for fire forming brass finished the next step is fine tuning a load for the Ackley cases.

 

The newly formed Improved cases were cleaned and neck sized only. A charge of 46.5 grains of IMR 4831 was found to be an accurate load at 2730fps producing a 0.132” 4 shot group at 100 yards. The Sierra 123 MatchKing bullets settled in at 0.025” from touching the lands in the bore, further powder increases proved that at 48 grains of IMR 4831 and 2800fps another accurate 4 shot group printed at 0.149” at 100 yards. It seems IMR 4831 is the powder of choice for this rifle, again I stumbled across an accurate load with my first powder choice. In conclusion the loads developed for this rifle are safe in THIS RIFLE and should be worked up gradually if used in another rifle, while checking for pressure signs. This was a very enjoyable and rewarding project build and proves that an M96 Swedish Mauser action can be built up to be a very accurate and safe shooter. With less than ¼” groups a common sight it proves that a 6.5×55 Ackley Improved can really drive tacks! As I look out the window and winter melts away I think about egg shoots coming up in Michigan in a few months, I may just show up at a match with Miss Ackley and enjoy a day with this fine shooting ¼ minute Mauser.

Bore Cleaning

Bore guide

 

 

 

 

Rifle barrel cleaning
Bore guides– If you don’t have one get one! Without a good one the cleaning rod could damage the bore, chamber/throat area.
Solvents – I use Sweets 7.62 for copper, Hoppies #9, JB Paste and Kroil.
——————————————————————————————————————

One Insert bore guide into receiver and chamber.
Two Run one wet patch of Hoppies #9 through the bore and let soak for approximately 30 seconds. Then run a correct bore size brass brush thru the bore (one pass for each round fired) another wet patch of Hoppies then dry patch out the bore.
Three When passing the cleaning rod thru the bore use a folded paper towel and hold it against the muzzle. this way when you feel the jag or brush exit the crown you can guide it out and back in to protect that expensive barrel.
Four Follow the instructions on the bottle fo Sweets 762 solvent and clean until no copper is evident.
Five Use JB Bore paste along with Kroil to remove stubborn deposits and follow-up with JB Bore shine (follow instructions on jar of JB)
Six I follow by applying a patch soaked with LOCK-EEZ This is a graphite powder suspended in a solvent that coats the bore slightly before that first round fired through a dry bore. ( I picked this up at a NAPA auto parts store ). Clean out the chamber with solvent to remove any graphite and lightly coat with kroil if you are not going to shoot until a later date.
I have found this ( Lock-eez ) method to reduce if not eliminate those first round flyers.
Patch colors:
Green = lead
Blue = copper
white = Clean bore

As for cleaning rods I use stainless steel and coated rods. One piece! stay away from the screw together sectioned rods especially aluminum (partials can embed in the rod).

Clean bores and tight groups keep rounds in the X-ring

Remington 783 range results – part 3

Remington 783 range test:

With the Leatherwood 4-16×50 Uni-Dial scope locked down and torque along with a quick check to the stock bolts for torque. I tested two powders with the 243 Winchester cartridge one being IMR4064 and the other IMR4831, this barrel did not like the IMR4064 and would throw flyers with each group. IMR4831 proved to be the powder for this barrel with a final charge of 46.5 grains under a 70grain flat base H.P. ( these were unknown maker brand bullets I found around the shop and are light for the fast 9.125 twist barrel). I did find this cartridge stretches quite a bit after two firings and needed trimming along with neck/shoulder annealing. Full length resizing dies proved to be better than just neck sizing the cases and bullets seated -.010″ from the lands settled the groups right in there.
* THIS IS A MAXIMUM BOOK LISTED LOAD AND MUST BE REDUCED BEFORE LOADING FOR ANY OTHER RIFLE OF THIS CHAMBERING*
Velocity was measured at 3150fps from this short 20″ carbine barrel and recoil was very minimal. I didn’t test accuracy with factory ammo to verify the claim of sub moa out of the box since a light for twist rate bullet was used, extraction was smooth with one finger to manipulate the bolt along with a very snappy ejection of the spent cartridge.
The importance of this article is to show a $250.00 rifle can shoot sub moa right out of the box with quality optics and good loads. Nothing fancy no jewled bolt, high gloss wood or bluing just good solid accuracy. Five shot groups at 100yards with the cryno set at 10′ from the muzzle, 40 degrees F, cloudy dark day.
