Well the 4.3grn loads never shot any better. (About 12" high and all over the place at 10 yards) I am at a loss here of what to do. Bump the charge up to 4.5grns? Try a different boolit that's not hollow based?
Try a .452 sized 250 gr SWC bullet thats harder.
my guess is its the soft bullets deformoing to much .
most guys that shoot the smokeless in theses shoot 5 gr unique loads but 4.5 should work decent as well.
has to be your bullets is my best guess.
