When I had a .380, I found at least one like this in every box of WWB. Also had one with the wrong size primer or something; the base of the casing was punched in and the primer was barely seated. I didn't shoot that one.
I've seen that in a box of WWB .45. It surprised me, but I think the quality control for some ammo manufacturing has gone to hell in the company's haste to cash in on the Obama Factor.
When you buy ammo in the quanities i do and shoot as much as i do you will notice that every company has occasional issues like that. They cant check every single round that goes out and sometimes you will get rounds like that or rounds with no powder or a double load, or any number of other issues it just happens.
good reason to learn to reload....besides it saves dollars. but you ammo buyers keep it up..... you provide me with new brass every time Igo to the range...........
