I have recently been shooting a replica Rem New Army and Colt 1860 because they are alot cheaper to shoot than cartridge guns. I have found they are both capable of accuracy on par with my cartridge guns.What I do have issues with is the nipple / cap fit. The rem has nipples that are too small and I have to pincht he caps to get them tight. The Colt had nipples that were to big and I had to turn thenm down to fit. none of these are really satisfactory fixes. Where can I get some really good nipples that will properly fit no11 caps? I don't mean which retailer, but what company makes the best product?
