Federal Primers Pierce. Heads up

[Kim Woodrow]

Were these factory or hand loads? What was the temperature? Was your ammunition exposed to sunlight? I ask these questions because all of these can effect pressures.

I never Shoot enough rounds to get my barrels hot 6 or maybe 8 rounds.

how do you have that self control? i have to take a quick commercial break so i dont melt the barrel down.

 

[Reloader222]

I only shoot Federal Primers and for 30+ years I never had any problems with them. If you show us a photo we can perhaps help.

Dang it...I really hope this is a rare and isolated incident as I have many thousands of Federal primers (who doesn't stock up when they buy?) I'm surprised Federal seemed so disinterested in the problem. A pierced (firing pin) primer is one thing, but to have a hole appear elsewhere in the primer seems like a defect the manufacturer should have more interest in. I would love to see a picture of the hole in the primer if you have one to post. I've never seen that before.

I had that happen a number of years back in my 7stw with a couple of 215's in a known good load. It was in brass I bought used... Tossed the brass and no more failures out of that brick and I'm probably a couple bricks past it too.

I have 7000 Federal primers, some are six-seven years old. When I buy them they go in the vacuum sealer and date marked plus it's very dry here in Az and they're in the house with the AC going all the time. Take a few hundred out and reseal the rest. Never any primer problems.

What kind of brass were you shooting when this happened

I was shooting Remington 7stw brass that had been shot by someone else and traded to the gun shop where I bought them used.. It's not always the primer; sometimes it's crappy support from the brass combined with rather high pressure loads.

They are known hand loads 80 deg.

Louis,
Were these the last 3 rounds or no?
I think we all fell into a trap of thinking we know it is the primer. It may well be, but it may also be possible something was on the bolt face in that area.

They were random. The bolt face is fine except for the etching even now it is fine to shoot. I shot it several times after the last primer failure.
