Shot it for the first time Saturday. Seems a bit over gassed. Brass was landing 10-12' away and the brass was beat up pretty bad.

First up was a box factory Winchester 150 PP to zero and check cycling on the center target. This ammo shoots about 1.5" in my bolt gun so I was not expecting much. Had one box left so used it here.

Then 3 rounds of SSA 168 gr match factory rounds to check accuracy potential on the left upper orange dot. This was only 3 rounds, but they show great potential for this barrel. Now if I can duplicate that load. That factory ammo shoots the same from my bolt gun.

I had loaded 40 rounds of Hornady 155 amax with a mid range load of CFE223 just to break in the action/barrel, but only fired 10 rounds on the right side of the target.Those were just a tad on the hot side so I will reduce the loads a little. I was not aiming real carefully, more focused on checking the cycling.

My AR15s have adjustable gas blocks and I have them tuned to where they shoot reliably but soft. Brass lands 3' away. I am planning on getting a adjustable gas block for this AR10 and hope to soften it up a little.



Great report on your new rifle. Good luck with it. It looks sweet and one hell of a good deal.
