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.
