My old SAA is a 32-20 and it’s a 1898 and thus isn’t rated for smokeless powder. The very next year however, they were rated for smokeless. So I have shot it with black powder but the corrosiveness and disgusting residues make me feel like I’m not preserving the piece like it should be. So after some research I’m thinking about using smokeless and making some light loads for it. Reasoning being that because metallurgy didn’t make huge jumps in the colt factory in a single year, and that by being a 32-20 it already has a lot more meat on its bones than the 45 cylinders, that it could probably handle smokeless just fine. What’s the lowest pressure smokeless for this application? Trailboss? Or should I be looking at black powder substitutes?
