I was shooting my g23 and i had a ftf, surprised me because this has never happened before. I erected the round and gave it a quick look and didn't see anything strange so i continued to shoot, i loaded it in my next mag and it happened again. Then i saw the end of the case had a ring around it, when i measured it it was about.031 longer than the rest of the ammo. No big deal as it didn't hurt anything but has anybody seem this before? I realize stuff gets past qc once awhile and better with target ammo than sd ammo.
