I have used bismuth in all of my waterfowl guns for about 25 years now. This includes vintage muzzleloaders, damascus cartridge guns, and nitro proofed steel barreled guns.

In my vintage guns the bismuth is loaded naked (with card wads only, no shot cups). Have never had a single issue in all those years.
