NFB with patched GG bullets got 2.5" groups at 50 yards, 4" groups at 70 yards. In a few days I will be shooting three select loads at 100 yards, and hoping for 6-8" groups, although I believe this gun can do better. An adjustable mold for a smooth-sided paper patch bullet is in the works, thanks to the advice I have received here. Next run of BP loads will have the bullets sizer-crimped, because there were some low-pressure problems with the hand-fit BP loads.
