It shoots ok??

[B Nettesheim]

Im curious how brass can get inside a bolt, customer says it shoots ok. Im guessing it will be a bit better after the firing pin can land squarely lol. Sometimes just a little inspection can resolve problems.

Looks like it could be Winchester primer blanks that have been hammered flat by the firing pin stop.

Yes, looks like primer blanks, from whatever brand of primer. I'm sure you will but I'd get those out of there.

...and there's a good chance the fp hole needs bushed. That is the typical cause of blanking primers and, if he had several primers to blank over time, the edge of the fp hole will erode, making it worse. I've seen the fp tip to erode on a few as well, again, making blanking of primers more of an issue than a smooth fp tip.

This is why you should not continue shooting a rifle that blanks primers until you get to the root cause and fix it.

Nope. Those are definitely shims to orient the bolt into battery squarely...

They are a little bit big I think to be primer pieces
About.125 on diameter.012 thick

If that's the firing pin hole they are sitting next to, They are quite a bit smaller than that, Which should be less than 0.080 firing pin hole. They were thicker when they blanked out, But then got hammered flat somewhat.

had a friend bring in a rifle that "wouldn't go off", unscrewed the firing pin assembly and primer blanks poured out of the bolt like confetti after a bushing job it's been fine ever since.
