Well - I think , as long as any "projectile" is wrapped in a patch , therefore not touching the entire barrel , EVERYTHING suitable could be sent on its path - BUT - forget about precision !
Me , for example , am shooting cast lead buckshot .290 ( pure lead ) round balls from my Ruggles underhammer pistols , which I cast in a Marty's Arms buckshot mold , only cutting off the ingot/sprue without any more work involved , and no matter , where the cutoff is when loading - when I shoot'em . even in competition , they hit just OK for me .
I'm practicing at 50 yards , I think , the three "8"s were my fault
