I know its been a while but we had a medical emergency and as you know time goes by.
I did go to the range and had several mis-fires. A friend was there and he gave me several rounds of Russian match ammo that shot consistantly. I checked and found the rims seemed to be thicker than the rest of the ammo I had with me. Excessive head space started ringing in my head again.
I went home disassemled the rifle and drilled out the lower toggle pin that I couldn't remove before by using progressive bigger drills so as not to touch the bore. When I finally was able to get the pin out I discovered it was in two pieces. In other words it didn't make any difference which way I tried to punch it the piece being punched was hitting a solid shoulder.
I installed a new pin from The Ballard Rifle Co. and reassembled the rifle. The block raised approximately 1/16" in the rear and stayed aapproximately at the same level in front where it mates with the barrel. Now it is very tight indeed but the action now is smoothe as butter. The excessive head space issue still exists. I can close the action with a .019 piece of brass shim stock between the block and barrel, the firing pin then protrudes out of back of the breech block about .035-.040. I can release the hammer and get a very nice indentation on the brass shim stock.
I believe I am going to have the barrel set back 1 turn and have the head space adjusted correctly. Shoot it for a while and if accuracy is poor then reline it for long rifle with the correct twist.
I would never have believed worn pins could ever caused problems like this. The one thing that still has me mistified is how in the world did the head space ever get so far off??? The extractor nor barrel appears to have been modified in any way.

Yes its tight with no shell in the chamber. However I think that in the process of trying to remove the bottom pin in the action link, the pin is probably "Flaired" from the punch strikes.
I thought about drilling the pin out but decided to leave well enough alone and leave that up to a "Gunsmith" in case it turns into having to install a larger pin. I am going to try and go to the range today and shoot a few rounds and see how many if any "Missfires" I get. I agree, I think it will loosen up with a little use.
Also, I am thinking seriously about having it relined, after checking the fired long riflle cases against a short, I am now convinced its chamberd for .22 short with wear so much as to accept a "Long Rifle".
