Title: All my 10mm brass has a small crease
Post by: Sorbz62 on July 17 2019 11:49:33 AM MDT
Hi guys,

I have just noticed that all my 10mm brass (from commercial ammo) has a small dent/ crease on the side of the case about 7.5mm from the top. I shot these in a Glock 20 with KKM barrel, so wondered if they are marks from the ejector and whether it is safe to reload them?

They should be just fine, usually the expander plug will push them out just fine.

What may be happening is the extractor hold the brass too tight, and being trapped hit against the returning slide. 
The sizer will take most of that out and the expander and bullet seating would likely finish the process...

Yep, I see those on my brass periodically, but are ironed out most of the time during resizing

Load em up and shoot em. That's no problem at all.

Wow, it must be nice to be KKM.  When we make a barrel, if the brass comes out with the slightest hint of a scratch, the customer calls and bitches about it.
