308 primer seating issues

[PowPow]

Oh, and BTW, it is was a big problem, why would commercial reloaders use Dillon 1050 machines, which swage the primer pocket for every reloading??????

You were pondering what I was pondering.

Okay, crucify me, but we are getting a ways down into the weeds, aren't we?

If you are actually working the brass each time you swage it, the primer would get harder and harder to seat.

And measure your case heads. How much to they change in side?

Hmm, ever notice that the sizing die does not actually size the case head? It stops above the web.

And finally, have you ever had a case head crack?

I notice that you don't know as much as you think you do.

Just finished a batch of .308 reloads. Encountered 2 cases with a heavy chip gouged out of the chase head, radial from primer pocket to rim. Deep enough to raise a burr of brass which interfered with seating the case into the shell holder. I have discarded them. Curious what could create that type of damage? My brass is range pickup so I assume its from someone else's rifle. Only seen 2 in the hundreds of cases I have reloaded, so I am not concerned its my rifle, just curious. Enquiring minds and all that.

Circular? Imprint of ejector from a bolt face. Probably from AR10 or MG.

not circular, a line from case rim to edge of the primer pocket.

Trying to diagnose a problem without seeing it, might as well ask a blind man.
