My original post on "buck and ball" seems to be lost somewhere, but anyhoo, I tried the .32 cal balls on top of and underneath the patched .490 ball with no real luck. Some real wierd patterns was the only result. So I guess buck and ball loading in 50 cal rifled barrels are likely a loosing proposition. Tried the .490 patched balls alone with great results. Also tried some hardcast .44 flat nosed bullets in in sabots (UGG!). Those shot fine as well. I am very happy with my 'parts gun' that I've put togther. Took awhile but it was worth it.
