Military Wiki Explore. Popular pages. Project maintenance. A grain, well-constructed bullet moving at about 2, fps is to yard bad medicine for just about anything, including bear and moose. It's certainly big enough for elk, and there's not a deer alive that will walk away from a solid hit.

The energy of such a combination is 2, foot-pounds at the muzzle and, within yards, it doesn't weaken much. That puts it squarely in the territory of the modern. The mighty.

Both Remington and Winchester produce bulk bullets in. Whatever your preference, bullets won't be a problem, nor will the large pistol primers this case uses. It's a very easy case to load for, as long as your dies don't push the minimal shoulder back. The one component that is currently in short supply is cases.

My test rifle is a Rock River A4 upper and lower, flat top receiver with a scope mounted on medium rings. In my opinion, yards is this rifle's practical hunting range. Good shooters will no doubt stretch that a lot, with high BC bullets, but big game is way different than steel gongs.

After the accuracy testing, the more precise, higher-magnification scope will be replaced with either a 3X or 4X ACOG or a red dot for faster target acquisition. The rifle is fitted with the Rock River match trigger, but no other modifications are made — pretty much stock as delivered by Rock River Arms.

Rock River offers either complete rifles or just uppers in. As of now, they only offer a inch chrome barrel with a flash hider good to protect the crown, even if you're not concerned about flash , and no front sight. I wish an or inch barrel were available. It would quiet things down quite a bit and probably add a bit more velocity. The Rock River line is known for quality, and this rifle is no exception.

But were I to have their ear as to the design, it would have an elevated optical platform EOP to get the scope up a bit higher, and a real recoil pad! For all the myriad of aftermarket parts available for ARs, volumes of catalogues or aftermarket goodies, no one offers an A2-style buttstock with a real recoil pad. The standard hard plate, more than adequate for the. I have it on good authority that DPMS will be offering an A2 buttstock with a real recoil pad in the near future.

Stay tuned. Dies ordered from Hornady have not yet arrived. Pulling the bullet showed a powder charge of A lot of powder room was left in that case. I'm anxious to work up reloads, but you can't hotrod AR loads. They must be loaded to a narrow pressure. Velocity range or timing goes to pot and reliability suffers. Hot loads are more trouble than they're worth. Over the chronograph, velocity 15 feet from the muzzle measured 1, fps with a deviation of 18 fps — very consistent performance — and it showed on the target.

A bit on the results before I go on. If you're like me you soon get pretty suspicious of gun writers who seem to get sub 1-inch, yard groups from everything they shoot. Maybe they have a magic trigger finger. That's not the way things are in the real world.

That is extraordinary accuracy from an unmodified semi-auto rifle. I am not surprised. Short cases moving heavy projectiles at moderate velocities are usually capable of excellent accuracy, but this is exceptional.

I fired about 50 rounds downrange, all fed from standard round. There was never a failure to feed, it never jammed, or gave me a problem of any sort. This AR design likes this load. Other loads for reloaders are available from the Teppo Jutsu Web site, and a lively reloading discussion is always underway at the.
