I tumbled some brass I picked up at the range. Some was mine, some was other people's. It all appeared to be 9mm as I handled it through the various stages, (picking it up, tossing it into tumbler, shaking out the media, tossing into casefeeder).
I pay what I think is reasonable attention to the brass, watching for splits, case deformations, and rocks wedged into the cases.
This caught me off guard. On the down stroke of my press, it's a 650 so it's moving the shell plate up, there was unexpected resistance to pushing out the fired primer.
So I stopped. I took the case out and looked at it. I don't know what it is. Which is the point of this post (yeah, finally, right?).
It's the size of a 9mm, or awfully close. The headstamp has either a "50" or a "30", a "9", a star and a triangle on it. The reason that the primer wouldn't punch out is that instead of having a single flash hole in the center, it has two flash holes.
Any ideas what this is?
And yes, I'm adding another step to my routine - check the inside of the brass to see how may flash holes...
Thanks.
