I have a Uberti 1858 Remington New Army, and am thinking of getting a conversion cylinder to allow using center fire .45 cal ammo. I have a Ruger New Vaquero .45 Colt, and I reload for it. I have been loading 250 gr laser cast lead, with 8.4 g Unique, and 6.2 g Bullseye. My question is can I shoot these rounds after conversion, or do I need to load a little less powerful round ? Any ideas would help, thanks.
