Case Broke in Half

[Socalal]

This case ejected from my Mini-14 in two pieces. The Mini often dents brass in the middle and I wonder if this case was ejecting, then hit something and split? Anyone had this happen to them?

Did it spit out both pieces?

[Socalal]

The Mini did spit out both pieces and load the next round.

Reload? If so, maybe sized too small/too many times?

[NoHeavyHitter]

I wonder it that case had been reloaded? They usually split (head separation) at the stretch zone just ahead of the rim..

The way that split, I would inspect and thoroughly clean the chamber.

[Socalal]

It was a reload and I think it was the first time reload. It was not a max load.

Do your other cases have rings on them

[TKM]

Who reloaded it?

[bohoki]

looks thin what is the headstamp/brand?

[readysetgo]

Dropped on the carpet?

[Two Shots]

Could it be that the case was below minimum OAL and stretched ?

Wrong burn rate/pressure curve perhaps. Case is not finished expanding when the bolt trying to extract, and the case is still plastered to the chamber wall.

That brass has been over-sized too many times.
If this is brass that you loaded, you should look into adjusting your sizing die so you are not over-sizing the cases anymore.
