Got out today to put some more rounds down this barrel. I only had it out that first outing with the 52SMK. I wanted to shoot some 77 SMK. I loaded some up with 23.2gr TAC.
Super slow for a 20" barrel at 2584.. Should be in that 2750-2800 range.. They started shooting though, Im going to do a load workup and see if these groups tighten up any before switching to 8208, AR Comp or H4895 to test.
Here are a few 5 shot and 10 shot groups. I didnt have a lot of time with the storm on top of me. Wind was blowing good and raining. Looks promising though!
Here also 2 groups from some 69 TMK/8208 ammo I had laying around. Speed up where it should be and much better SD's than the TAC....

Just got back from testing some TAC charges with 77smk since 23.2gr was super slow just under 2600 and some PP2000MR with 77smk..
Both did really well, found velocity I was looking for in that 2750-2800 range, no pressure issues, and shot some really good accuracy wjth some charges..
Looking forward to play some more with PP2000MR. Ill post targets in a little bit when I get the info downloaded

Yep, MEGA SBU thick walled upper and mega billet ambi lower. I grabbed a bunch of those MEGA SBU thick uppers when ZEV bought MEGA and they were dirt cheap
