Thanks everyone for welcome and advice. The pistol is a Pietta 1858 Remmington on 44 cal. The manufacture suggests a .454 44 cal. lead ball. Can I use a .454 44 cal. bullet of anything other than a ball? Such as a conical or wadcutter? The riffle is a CVA 45 cal. that I've been loading with 45 cal. powerbelts. Can I use a 45 cal. round lead ball on it?
