Got some federal premium ammo in .40 at walmart about year ago went to range last weekend, had a ring around the primer after its fired come off in the and stay in the gun. Was not happy with this tiny brass ring's building up had 3 in myPPQ and 1 in my jcp in the Q it they were back in the slide and down the side with the springs, jcp seen it the on feed ramp when mag was empty just watch if you use this ammo
Ouch! I didn't see the mention of the JCP! Deadrock did you contact Federal? I would want to send the empty cases, and left over ammo back.
Then I trip over this thread. Federal ammo in 9. http://www.smithandwessonforums.com...forum/49679-glock-kaboom-new-glock-hater.html
