So far I've tried A2520, Varget and Lever. I settled on Lever so far. It was the best combination of speed and accuracy. With Lever I got 2700 fps and just under 3/4" @ 100yds. Varget gave me about 5/8" but only got it up to 2450fps and was already over book. A2520 was good also, about 3/4" but only 2640fps. Still gonna try VV540 and see if it improves any.
How did you manage that accuracy with a BA barrel? I've a BA 20" Premium Black DMR and couldn't get it below about 1-1/4 with three different powders and about 250 rounds.
Matter of fact I'm about to put it on GB since I've replaced it. It would be fine for hunting or ringing steel but the fuddish club I belong to won't let me set up my steel, and I don't hunt lately.
