I saw something on the Pyramyd blog about a 40+ fpe .30 cal 135 tuned by John in PA. I want something like that. Anyone doing this kind of work or was that a one off project? Now that I got my R9 sorted out I want this ultimate magnum breakbarrel.
I’m sorry it was actually Rich Shar (Rich in Mich?)
