I acquired a 20 Prac upper a few months ago, 20" 1:10 BHW. I've rolled through a ton of load dev using 32gr/40gr Nosler BT and Berger 35gr HPFB varmint and 4 different powders with each (8208, TAC, H335 and 10x) and best I can do is MOA. No, I haven't played a lot with seating depth as I haven't found a bullet it REALLY likes yes. Best I've done with this is the Berger and 10x at about 3800 FPS, but that's MOA at best. Doubt I'll ever use this past 300yds on chucks/yotes. I KNOW this setup can be much more accurate. Suggestions??
