Looking for something that has at least 18" of good barrel. I don't care about rust, or the muzzle. I'm looking to practice cutting it down to 18-19" on my lathe, but don't want my first try to be on a good barrel. Whether it is a plain barrel, or vent rib, or what have you. Just looking for something cheap to practice on that I can hopefully have a halfway useable product at the end. I'm in NWI and can travel locally for the right deal.
