I don't want to "make"barrels, I can't afford the machinery to do that, and I can't imagine trying to bore out a solid bar or truck axle by hand either!!!!!! I want to re-bore existing shot out barrels, or rifle bored and reamed barrels, purchased from a supplier. No one lists smooth barrels on the net and a few inquireries have gone unanswered. To order a custom barrel un- rifled cost as much as one that is rifled!!!Maybe my brainstorm is not such a good idea and I should leave all thsi up to Getz, Rayl, and Hoyt???....Ed
