I would prefer blue. but I would take SS or blue. I e-mailed Green Mountain. Maybe they can tell me where to get one. I think that would be a great barrel. If you see one anywhere would you please tell me. I am not in a big hurry, so I can look around for awhile. I just really like the idea of the 1in18, and being able to use all my 45-70 molds is a real plus. I wanted to buy a paper patch mold for my 45-70, so this could work out perfectly. I am assuming you are sizing your paper patched bullet to .457?? Thanks, Tom.
