I've been working on a Pietta 1860 new army cap and ball revolver kit, .44 cal that I bought from Dixie Gun Works, and have just finished. The info I read from Dixie recommends a .451 round ball with a max charge 22 grains of fff black powder. but the Pietta handbook that came with kit recommends .454 round ball with a max charge of 15 grains of fff black powder. It any of yawl Pietta owners out there could tell me what has worked the best for yawl it would help my confusion greatly. Thanks.
