hull loosing primer when fired?

sarg1c

Well while down at the restaurant drinking coffee with the guys, one of them produced a 7mm-08 HULL WITH OUT A PRIMER, NEW REM 700, NEW REM AMMO After extracting hull, had to shake primer from actiom...what gives.. This is the third hull like this. Is it headspace, or bad hulls. How did primer get out of hull. No smoke on hull except where primer came out. ???

Call REM with lot #; they will make good on the ammo.

Probly bad ammo.

Impossible to gauge headspace in ciber space.

Sure it's a 7-08?

OEM factories make mistakes just like anybody.

I have found anomalies in Speer Gold Dot and Federal HST factory ammo (1 each) over the past 15 years or so.

Headspace problems cause cases to separate just ahead of the extractor groove. Primer pocket expansion is a result of massive overpressure. Stop shooting that ammo and call the manufacturer. They will probably send you a shipping label to return the damaged cases and the unfired rounds.

Here's an example of going just a bit too far with load development on a wildcat cartridge:



OOPS!

Thought we were gonna be talking about fired shotgun shells........:jester:

Very well could be overpressure, as the others pointed out.

What I'm saying is, make sure some kind of screw up didn't happen......like his rifle is a 7RM, or a 308, or a 260.......something along those lines.
Stranger things have happened, than a salesman giving someone the wrong product.

All I saw was just one of the hulls 7mm-08 Rem. I'll be down to the restaurant in the morning all maybe he will have the rifle and he should bring me one of the hulls.still don't understand how primer got out of the hull with bolt closed May be so loose primer fell out when ejected....I couldn't see this much headspaceing..This is a new rifle and marked 7mm-08.ALSO NEW AMMO with three doing this. I would have stopped with first round., still any of the .308/30-06 spinoff round the bolt should have held the primer in the hull. Now remember, I just quoting this guy. I'll find out what really happened...Barrel could be marked wrong.
