A HBC man wrote in 1847 that there was no point in buying a rifle as a fusil loaded with a patched ball will shoot ‘as well as a rifle to sixty yards, and most game is taken in that range. The patching he wrote about was the finger tips of worn out gloves. As I’m sure he would shoot more then ten shots till he wore out gloves I think it safe to assume he used regular or maybe thin leather patches at times.
of course it doesn’t shoot as close as a rifle, but shoots better then many shooters get from modern guns when in the woods and easily as well as slug shooters with a shotgun.
