Does anyone know what causes this

Primer is extruding back into the FP hole in the slide for whatever reason, then shearing off when the barrel drops to unlock. May be caused by soft primers, a gun timing problem, or an undersize firing pin.
The firing pin channel will rather quickly become packed with brass shavings and cause misfires eventually.

Notice the headstamp- Corbon- probably high pressure loads-

Primer flow. Excessive headspace problem.
Mine were probably overloads. 
Since I sized them on my Projector, way back when, I may very well have created artificial headspace. I just recently set up my dies on the LNL and was much more careful setting up the sizer.

cases
those are 400 cor bon.they must have been loaded hot to cause the primer to be sheared like that.I dont like the idea of a bomb in my hand.but alot seem to not care.

headspace
how do you change headspace on a straight pistol case?

Starting at Post 4 or 5, we have two different conversations going here. No problem, as long as we keep ourselves straight.
The OP says that this is range brass he picked up. He is not overloading his ammunition. The previous shooter did.
Stang46gt - Those two cases may be OK to load and shoot, but pay attention when you seat the primer. If the new primer slides right into the pocket with no resistance, the case is unsafe. The case head (including the primer pocket) expands slightly with each normal firing. But it expands a lot when overloaded, so loose primer is the bad sign to look for.

The problem is the brass
PMC stands for: "Poorly Made Ammunition"

Actually, PMC ammo is quite good. It's made on top grade machinery and I've never had a problem with any PMC ammo I've shot. (both handgun and rifle ammo)

I've been reloading PMC range pickups for my .45 with great results.
I haven't shot their ammunition, but I can't complain about their casings - I've had some great groupings using reloads in PMC brass.

Nope.
WRONG!
You, sir, should never stay out of a discussion in this forum.
