Pretty hard to tell what any given gun will shoot good but every CVA Ive owned shot XTPs really good either 240 gr or 300 gr under 90/100 gr of pyrodex RS, should be able to get it to shoot good with that or 777 2f..my advice is try to get a range of 4-5 or more different bullet/sabot combos and experiment w/powder charges etc till you hit the right one, start low say 70 gr and work up.
