Anyone Care to Diagnose?

[TaterInTheSouth]

My father-in-law gave me this box of brass that a friend gave him
to give to me....try to keep up.. (Grin)

When I opened the box this is what I find.
Every single primer has leaked and one is MIA. I am trying to track the
rifle down so that I can go threw it and rule it In or Out before I try to
contact Winchester. This was new factory loaded ammo.
What are your thoughts?

Over Pressure. Dont know why, but thats not good.

First guess would be running in a semiauto. Just a guess but if it's like the Hornady Light Magnum ammo than it is too hot for the action. Second guess would be a semiauto unlocking a little too soon.

Look how far off-center the firing pin strikes are. Weird?

The M1A can easily run more pressure than a bolt gun. That is what it looks like.

Headspace?

Don't think M1A will run higher pressures than bolt gun, unless you'd want a piece of the receiver heel imbedded in your face. Push the M1A and you can hear a extra "ringing" sound, that would be the bolt peening the back of the receiver, which is keeping it from flying into the shooter's face. If I was the OP, I'd just pitch the brass in the brass recycle bucket. Its not worth the risk using unknown brass that shows clear signs of abuse with the blown primer.

1) Headspace issue in the 308
2) Running hot bolt rifle only factory ammo in a gas gun (like the Superformance Ammo in an AR10 or LR-308)
3) Shooting 308's through a 7mm-08

Re: Anyone Care to Diagnose?

When I first got into shooting, I had a couple blown primers and heavy ejector marks due to leaving my cartridges laying in the sunlight while i was shooting on a 100+ degree day.... you might ask the guy if this could be the case.

Not a Whole Heck of a lot I can do.....
It is a single shot breach loader, new from Acadmy Sports, CVA 150.00, He had no clue the brass was stressed.

Re: Anyone Care to Diagnose?

Since all the primers had issues i'd scrap the brass. Why take a chance the primer pockets are loose and cause yourself a problem.

Re: Anyone Care to Diagnose?

Decap it, resize it, then inspect it and see if everything looks OK. If so, try to prime the cases. If the primers feel loose or don't seem to seat properly, then scrap that case. Unless there are other signs, there's probably not anything wrong with the once fired brass. Clean it up and inspect it. If it looks good, see if they reload well.

Re: Anyone Care to Diagnose?

What do you mean? That it can "cope" with more and be run hotter?
If that's what you are saying what are you basing it on as it's simply not true.
