Hi - be gentle on me if I don't use the right terminology.
My Jr. Olympic Rifle program has some old 22LR Anschutz rifles - maybe from the 60's. They are great for the younger shooters because they are light. On one of them the surface that cams the bolt completely forward into the battery is worn so that the pin does not strike deep enough and it will not fire. Swapped bolts around and the same thing. If I put a piece of ammo box cardboard in there to help wedge the bolt forward more it fires fine. There is a light burr on the surface and it is clear that it has worn down some.
So - how to repair. I was just going to measure the current gab with a gage block and then build it up with some tig and then machine it down using gage blocks to hit the the slot dimension that I want (about 0.014" more). But they I started wondering if its hardened or not and how long such a repair would last if I ended up annealing the area.
Any advice?
