issue with 29a bolt assembly/firing pin



Log in to see fewer ads
Since last message on this topic; I decided to take photos of the bolt.
I removed bolt from rifle and the extractor and the firing pin were moving pretty freely; in fact, the bolt wasn't dirty but sprayed out with brake cleaner anyway.
Replaced into rifle and still no indention on casing when gun fired.
Here are some photos I took:

I can't see anything that looks wrong in your pictures, the front of the firing pin should be even with the face of the bolt when retracted, and it appears to be. The rear only protrudes about 0.025" - so the front will only stick out that small amount with the hammer down as far as it will go against the rear of the bolt. This is done to try and keep the firing pin from hitting and damaging the edge of the chamber.

Measuring a firing pin I get 2.115" overall, it that's 0.025" or more short the hammer will stop on the rear of the bolt before hitting it, or uneven wear on the hammer may keep it from fully contacting the firing pin.

I would try to put a few small piece of heavy tape on the rear of the firing pin and try firing it to see if it then will mark the rim of a case. The tape might be to soft to make it fire, but it might at least make a mark if the problem is with the firing pin.
