My new R700 barrel.

A few months back I ordered a 22" m24/m40 contour 450 bushmaster barrel for a R700 action from http://apachegunworks.com/

I screwed it all together last week and these are its first shots at 100. 4 shots at 3 o'clock are the very first shots fired, I had a magnetospeed attached. At 12 O'clock is a second 4 shot group also with the magnetospeed. 9 O'clock is 4 shots without the magnetospeed and the final 4 at 6 O'clock. This is all with Factory Hornady ammo using the Flex tip 250 grain bullet. Velocity published on the box is 2200 fps.

Image

IIRC, the 2200fps is what is to be expected from a 20" AR gas gun. My 22" barrel on the bolt rifle gave the following:
Shot Group 1. 2343, 2339, 2312 & 2364 for an average of 2339 ES=52 SD=21
Shot group 2. 2329, 2318, 2365 & 2320 for an average of 2333 ES/SD 47/21

So I am pushing these about 135fps faster than the published velocity.

Business end

Guess I ought to up date this thread a little...

Open day at ~11am (Nov 15 2015) this guy came by.

I was tempted to let him pass and hold out for something bigger and more mature. But from 30 yards I could see a patch missing from his neck and exposed muscle. Figured I'd save him pain and possibly death by infection. One shot from the bushmaster double lunged him and after a little sprint he was spent. Notice the hole it left on the exit above, about a 1" exit. Also note the neck wound below... looks like a puncture rather than a gun shot wound like I first thought, as I don't see torn muscle like a gunshot would normally inflect.
