Hi I'm new to Carter's just bought a Buzzard from Donkey Oatey. I am quite familiar with Nelson's but this will be my first Buzzard. I've read that the internal ID of the barrels is some ware in the .690 range. One thought I had was to get a PPS Autococker barrel in .680 with wedgits. Looking at their barrels I have for other guns I realize they lack the taper. I also am suspicious that they may be to narrow for the pump. Has any one tried this? I'm guessing that if I go this route I probably need to call and see if they can do it custom. Might be better just to get wedgits on the stock barrel. Or a new one from Carter's.
