A friend is going to have a custom action for sale pretty cheap. Thinkin of snatching it up for a 7 Sherman Short build I've been wanting to do. I know I want a carbon barrel but I'd like to have one that is 28" 1.250 straight contour. Curious if anybody knows if proof will do custom contours. I know carbon six will but I haven't heard many range reports on them. I know alot of guys are having awesome results with proof.
