Better solution

Remove the main bolt screw, turn 3/16" off the threads. then drill and ream the screw so it can be tapped .250 X 28tpi. Insert a .250 X 28 tpi X .750 cone point set screw inside the main screw.

Make a small shouldered cap for the cocking piece sleeve. Center drill a small dimple in this cap. Insert the cap in the cocking piece sleeve. Then screw the main screw into the back of the bolt. You can adjust externally the spring tension on your firing pin spring with a 1/8" allen wrench through the existing allen hole in the main screw. The cone point reduces the friction and make cocking much easier. This tackles to problems at the same time.
