I'm thinking for putting together a 7.62 x 39 Mauser. Rhineland has savage style barrels for the actions in small and large shank. I'm going back and forth on the pre 98 and post 98 actions. This brings to light the CIP vs PSI concern. Has anyone put one of these together? I'm also concerned with extraction issues bc of the base diameter. Any thoughts, concerns or stories on the idea are greatly appreciated.....
