Wow! I think the most difficult thing would be to get your hands on the reamer. You may have to get one made, I'm sure they don't grow on trees these days. Once you get the reamer, pretty much any good smith could set it up for you. What part of the country are you from ??? I know a great smith from Reedsville, WV. He has several state shooting titles and even a few National titles as well, as do some of his customers. HD1
