RE: Seasoning a barrel ??
I guess I might as well put in my 2 cents worth too.
I have use BB ever since they first put it on the marketin PRB traditional muzzle loaders I would not even consider using anything else; also for breakaway sabots.
Acombination of polishing[ not lapping the process is the same but you use a compound called jewelers rouge instead of a grinding compound and it only smooths the surface to a high polish] and using BB the way Sabotloader does has allowed me to use 777 without "crudring" and I had the worst case of that you ever seen.
As for the people that dont use it right, I never seen anything that someone could not come up with a way to miss use. Lee
