So here's something I haven't seen in the past. While resizing 40 brass mixed head stamp I have ran across 12 in 3000 cases that are huge all the way up the case. I know a couple cases are CBC brass.
Unsized normal brass.
Big brass.
Bulge is all the way around the case and a lot further up then the dreaded Glock bulge isn't it.
I started it into the sizer die a little before realizing there was a problem.
Here are a couple that weren't as bulged and made it further into the sizer.
So what causes this?
