I'll probably do some more testing on it but with a proper front rest, this was off a bipod. Also these rounds were made with brand new Hornady brass with only a mandrel run down the necks. I waiting for my AMP to come in then I'll do another ladder to make sure it's still good for this barrel now that it's got 900 rounds through it. Still for PRS work any of these groups are sub-moa and should be fine.You may want to try all the way out to setting 20. I confirmed by email with erik thats the end range. I had a few in my notes, as far as best performance and ended on 18 or 20 (cant remember). your group #8 looks pretty good, as does #6. I believe I had a similar experience around that setting, and it got even better for 18 or 20.
Ive shot it a few times since, and can confirm that staying with the same grain (140), the performance is consistent with different ammo. Shot federal gold medal sierra match kings and the groups were all less than .5 moa, even with larger sample sizes (5-10 shot groups). I'll have to measure my 200 yard performance as well, but it was my 3rd time ever trying 200 (with holdovers only) and 3 different 10 shot groups were all approx. 0.7 MOA
