1322 velocity after FTP and valve mod

[ray1377]

How do you retain pin in valve inlet when reducing headspace?

I'm late to the party here, but I have done what your asking. I used a piece of music wire I checked and found in the junk box that "just" fit inside the valve intake hole. I sharped the end like a needle. I have the complete valve out of the gun and then heat the sharpened end of the pin with a torch and get it hot. Then use pliers to insert it into the valve intake and into the delrin check valve. Hold it a minute until I know its cool. Then I took the valve apart and put a little super glue on the pin where it enters the check valve. Not much, a half drop will do. Once this is done I put the valve back together and use a dremel tool to cut off the pin where its just flush with the valve.

Thx
