Firing pin keeps breaking

[AlNyhus]

FWIW, with 700 bolts that have wonky theads, a wrap or two of Teflon tape around the shroud threads can be a good diagnostic move.

Given what has been posted by the OP what he really needs is a gunsmith with diagnostic capabilities. Which apparently is beyond the ability of gunsmith/gunsmiths he's used previously.

My vote is there is some crap lodged in the firing pin hole near the tip. Pull fp assembly and push a long punch through from the face and all angles possible, scraping the sides if possible. Blow out with compressed air.

Time send it to someone who knows how to examine it and repair it properly. Enough money has already been wasted on another new firing pin that is already bent. Sooner or later it will cause a larger issue than just a bent firing pin.

Yes that is the plan. I’ve reached out to the “bolt guys” on this site

Please let us know how this all works out. Sure most will wanna know in case we ever come across it ourselves.

They haven’t been talking any new work for quite some time.

Funny you should mention that. A buddy was firing his .223 M700 at dogs on a hot July afternoon, at about 15 rds a min. All of a sudden it wouldn't fire, looked and it had a blown primer -- really bad. Didn't work on it till he returned home. Couldn't get the firing pin to go down all the way and couldn't see anything unusual looking at the bolt face. Turned out part of the primer had near vaporised and retreated inside the bolt, blocking the firing pin shoulder. Took a lot of scrubbing inside the bolt body to remove it. He's been using this same rifle for at least another 5 years without problem. Maybe something similar happened and material formed to one side, moving the firing piece off center on it's way down. Sure ought to be able to see it with a bright borescope.
