I've got a carcano barrel that I want to re-blue. I understand that I can steam the barrel to convert the rust to black oxide, but what does the bluing solution do to the steel? Can I blue the barrel without any bluing solution? If I need a bluing solution, which brand would you recommend? Thanks.
Could be an oval bore like the 9.6x53 Lancaster. It wouldn't have any rifling or be firing a "fixed shotgun shell" making it a "firearm" under the NFA.
Decent roll up post about what happened.
