RE: What size round ball for .44 Navy pistol
Well I went to my grandads and cast up about 150 45.1 balls and about 50 .50 balls and about 10 or so of the 45.7 balls. I tried the 45.7 balls and they fit just a bit too tight for my liking. Now they work very well though in my grandads old Ruger 45 pistol though. Lots of work casting those things, but also pretty cool too.
