New to pistol calibre reloading but I have a Rossi conditioned for target, vermin and AOLQ.

I would like to load 158 gr cast for gallery rifle that will be slow enough to lead foul the barrel, 110 gr hornady XTP for vermin as fast as I can and 140 grain Hornady FTX fast enough to be small deer legal for anything else.

Locally i can source Viht, Alliant and Hodgdon powders easily, I'd like to stick to 1 powder as its a smaller outlay and keeps things simple, I have read on a few forums across the pond that Lil gun at 16-18gr is a possibility for the FTX so that gives me one option for that load but I'd still like a powder for all 3 if possible.

Anyone doing something similar and what with?
