I have an old Savage short action single shot that is currently barreled to a small shank 6.5 Creedmoor, .473 bolt face. I’m considering throwing a Shilen 6.5 PRC barrel on that action. Of course I’d need a .532 bolt face. I need a little guidance on the new bolt face. Does a short action magnum bolt face differ from a long action magnum bolt face? Also, where should i go to pick up the new bolt face?
