in hearing about possible reasons for the M1922 misfires.

I have a M1922MII that had the same problem. My firing pin tip had a chunk out of it and I was only getting half circle strikes on the cartridge and quite a few failures to fire. I replaced the firing pin and mainspring with new ones. After that I got nice circular strikes but still many misfires. I put the old mainspring back in and function has been 100% since then.

Any chance this could be a headspace issue on westgard's rifle??
