Bad primers. Is my bolt ruined?

[ko1featherweigh]

Had a bad batch of primers pinhole and pit my bolt face. I got a replacement bolt. Should I fix this? Plan to keep this bolt as a back up. This is on a gamer rifle.

WOW! How many shots did it take to do that?

I'd run it. And worry about it, if issues happen.

WOW! I over 60 years of reloading, I have never seen anything like this. What brand of primers were these?

Probably the course of 3-400 rounds. Ran it in a weekend match didn’t notice until after the match. Only difference I noticed was some smoky rounds.

These were Winchester LRP. To Winchesters credit they reimbursed me for all the primers I had in that lot# and paid for the new bolt. Funny thing is I ran a brick of 20+ year old primers with no issues, these were purchased in 2020

I have been real cautious about some of the foreign made primers. I have never had any problems with Winchesters.

Oddly enough, these were Winchester primers

Are we sure the primers were the problem?

Standard, safe protrusion for a Model 700 is typically 0.040” to 0.060”. I'd want to measure that and get the firing pin protrusion down to something like 0.050" if it wasn't already that or less.

A crap-ton of dry firing with nothing to retard the velocity of the firing pin can make the protrusion grow on a 721/722/700/40 X action. But I mean "crap ton" literally; the kind of dry fire that some match shooters do.

I'd at least want to rule out excessive firing pin protrusion, if you haven't already done so.

I had a couple Tikka bolt faces etched with Winchester primers.
