MSQUARED and others Being a golf pro, when the old leather grips were used the end of the shaft was filled with a rubber cylinder through it was a screw of 1/8 threaded rod in diameter with a nut on the end.A cap was placed on the end of the club and the screw inserted through this cap then the screw was tightened and the expanded rubber held the cap in place See the local golf pro he might have some, or a hardware store It is a simple tool that when you tighten the nut at the end, the rubber expands and grips from the inside of the case leaving no marks in or on the rifle. Most case bodies are only stuck because we cant get a grip on them and have no camming power to pull them out .
