I have a Bell @ Carlson Medalist stock for a Target Action single shoot (4.40" screw spacing) which I am mounting on my 6.5X47 Lapua. This stock I could get to fit my platfrom, was one with a blind magazine. My question is, if in the future I want to use this stock for a different action (a reapeater) how complicated it would be to adapt the stock to accomodate a detachable magazine (5-10 rounds)? Just wondering.
