Just getting back into shooting the muzzle loaders again after being out since the late '60's. Back then it was mainly round patched balls. Bullets for muzzle loaders was just starting. Now will be shooting cast lead bullets and saboted cast bullets. I know the saboted bullets do not need lube, but what about the cast bullets? Shooting a Knight .50 cal in line, straight cast .500. Sabot with .458 cast bullet. We used to use Crisco as a lube on the bullets. No such thing as sabots back then. Thanks much for bringing this old timer up to date a little.
