Well, upon looking at chamber dimensions versus cartridge dimensions, I'm thinking 44-40 is the way to go. The remnants of the current chamber's leade should all but disappear with the new throat. And the theoretical overage in the neck area is quickly diminishing in the 10 thousandths of an inch.
Nice bullet though, Ed. The gun has a 24 twist, so it should handle any pistol bullet I can cast for it, although I'd probably be looking for something a little shorter on the nose, maybe even a WFN.
