Im looking at having a 20gauge Browning Citori shortened and maybe having removable chokes if the barrel is thick enough. Can anyone recommend a smith and an approximate cost? The wild side of me is thinking of leaving one tube cylinder bore and the other tube getting a Vang choke. It will be a "barn gun" on a ranch and I was thinking it might be nice to have a wide open pattern with one barrel and being able to hold the pattern together out to 50yards with the second. Primary use will be dusting coyotes and other stuff that needs lead poisoning.
