I have had the same problem with the newer gold colored Winchester large rifle primers. This problem badly damaged an M1 garand bolt in my springfield. The problem is with Winchester's newer primers. I changed brass lots, used new unfired brass, changed Winchester primer lots, installed primers in very lite cast bullet loads and primers still produced pin holes that damaged the bolt. This problem has only occurred with large rifle primers for me. I stopped using all Winchester large rifle primers and only purchase other types of Winchester primers when no other brands are available. The old silver colored Winchester large rifle primers work very well but the newer gold colored primers are junk!

Just did my remaining Winchester primer inventory. Got quite a few of the primers from the two lots that I have had problems with. I'll switch to shooting surplus ammo until I get restocked. I found a phone number for Winchester in an old post from another forum. I called and left a message not really expecting a live person today.

Winchester switched from nickel plated primers (rifle, shotgun, pistol) over ten years ago. No idea where they are made.

My friend and I had the same problem with Winchester primers. Bought .308 match Silver State Armory ammo from Shooters Pro Shop. In the first 11 rounds, 3 primers had pinholes on the edge of the primer. They were brass colored primers. We stopped shooting them at that point.

Nosler (who had bought SSA last year and stated that the primers were Winchester) replaced the 25 boxes with new Nosler headstamped ammo. Now we have a 30% leakage rate (19 of 60 rounds) around the primers with several primers just falling out after firing (no pinholes). Primers are still brass colored. Nosler was saying that our M1A was causing the primers to leak.

Just a data point, here's what one lot of recent Winchester LR primers looks like. Which, actually isn't all that bad.



And here's what they look like in a couple relatively heavy Garand loads:


and



Looks like this lot at least is holding up - well, so much as you can say with a whopping 10 shot sample. But if FWfrench's data is representational at 33% failure - I'd say at least this lot (see lot number) seems to be fairing better. I'll start paying closer attention to this.

also, for comparison, here's what the S&B primers look like. Frankly, I think they look much better than the Winchester, and not sure where someone is coming from disparaging them.

Default Winchester primers

This 1903A3 bolt erosion is from Winchester magnum primers.
25g IMR4759 155 NOS, 1950fps.

I have 3 damaged bolts from WLR & WRLM primers.

I do not use Winchester primers any more.

Thanks, those are LR, not LP. Good typo catch.

Do you also defend their brass including the stuff they make for Winchester in 7.62x54 and .303? I also have heard of several others but have not used those. These I have and scrap any I find. The primer pockets are far too shallow and not worth the trouble to cut them. It's been about 10 years now that Winchester has been using the brass colored primers and I still think they are coming from S&B. I never said they were terrible primers, just making an observation.
