Also the spent cases have bulged primers. I've never noticed it in the past. 1 of the 4 spent cases in the pic have bulged primers...only 1 doesn't.

I have not had the best reliability from UMC or WWB in 9mm


Keep Calm and RTFU

I did some research & found a few forums where guys were having issues with the UMC similar to mine but they were from 2011. I even checked the recall ammo to see if my batch # came up but it didn't.

I'll shot some different ammo & report back.
