There is a gunsmith in Jasper, Alabama named Gallegher (spelling ??). Can't recall his first name right off the bat, but I will get it and re-post in the next day or two. This gunsmith was recently mentioned a gun magazine for doing a Ruger Vaquero conversion to 32-20, and the author of the article really praised his work.
I have talked to him about a barrel shortening project on a factory carbine barrel, and he was interested in the project, but I haven't had much time in the past year to do much of anything. When I get his full name (and correct spelling), I'll re-post.
