Use a good repro Remington New Army .44 and get a couple of extra cylinders. I also use the R&D Cartridge Conversion cylinder with .45 LC. Great shooter! I use the conversion often. I've put 100 rounds through it already this week. You can't do wrong with this Remington design. It's versitile, accurate, easy to maintain, and was historically the best revolver prior to the arrival of cartridges.
