Are muzzle loaders like other rifles where each one will like its own load? I have a cva wolf 209 and it dosent like sabots or imr white hots two of them, or any thing else i use It shots 320 gr cast bullet with 90 grn of black powder just fine if i put the white hots behind the 320 bullet it seems to keyhole the target at 25 yards. So am i screwed up or is thiskinda normal
