I’ve been plinking with muzzle loaders for hunting for near 40 years, and have learned a thing or two. My flinter is good for 4-5 shots before a damp patch wipe is required. Bullet guns might be ok for a couple of shots, but seldom more than that, be they lead or paper patched. One other item is bullet alloy. Pure lead works, and a tiny bit of tin won’t hurt, say 60:1. Don’t go any harder than that.
