A buddy of mine bought a BCA 18" heavy barrel upper and put it on a Stag lower with a single stage match trigger in it. Left it with me to work up a coyote load using 80ish grain bullets. He had a bunch of 87 Vmax and 85 gr Sierra Game Kings HPs. He and I both have 2 8# kegs of H335 we got super cheap, so I started with that. I was using new Starline brass. I seated the bullets so that they had plenty of clearence in the mag, and loaded 10 each just under the max load which ran them both thru my Chrono at 2750fps, give or take. I put a Vortex 4x12 on it to see how well it shot as this was going to be a hunting rifle. First shot at 25 yds, was dead on in 1/2" dot, 2nd shot egged the hole. I then went to 100 yds and it was dead on L to R, 3" high. I clicked it down and with 2 more shots had it zeroed on a 1/2 dot. The first shot hit the top half of the dot. 3 more egged out a hole, that took a little over half of the dot. This was shooting the V max 87gr. I then tried the 85 gr with the same exact load, shot dead on up and down, 1" to the left. 5 shots went into a hole smaller than a dime. I cant believe this crap I thought, this thing cant be that dang accurate breaking in a new barrel on a Ar. I had cleaned the barrel good and chamber before starting to shoot. The lower had a #2 trigger on it with a A2 stock which helped with cheek weld. I guess I should not be surprised since this round is basically a 6ppc with a different shoulder. He is going to be using it to varmint hunt with night vision, coyotes mainly. Just thought I would share this, as I was basically ho hum about the round, as I don't shoot a AR much. A side note, I have ordered 23 uppers from Bear Creek Arsenal and every one of them have shot sub MOA at 100 yds for 3 shot groups, some much less.
