I am unfamiliar with the Knight brand shotgun you refer too. The only Knight muzzleloading company I know of makes plastic stocked, pellet driven, primer fired, industrial shortcut specials, that can barely be called a muzzleloader. If thats what he is using, I have no idea or interest in what makes them perform. I think he's missing the fun, and bragging rights, if he's using an inline.
