T/C says Weathershield is a coating to protect the metal from corrosion, and rust. Is this better than a stainless steel barrel ? what about the bore ? I've always liked a stainless barrel on my muzzleloaders for its resistance to rust, and corrosion, over a blued barrel. I do know that you still need good cleaning practices to maintain even a stainless ML. How is the bore of a Weathershield barrel protected ? Is it more resistant to rust, or is it the same as a blued barrel ?
