I have an ultra low cost single shot 12ga wits no choke whatsoever. I've read about jug choking a shotgun, and I'm interested in trying it in my little single shot. has anyone cut their own jug choke? I was wondering if it would work to dress the stones of a mastercylinder hone in the shape of the choke, hone it out, then polish as a affordable coke for a cheap shotgun?
