ive actually had 7 failure to feeds in my M&P9 and 9L. all from the same box, 2 where the bullet was actually ripped out of case either on the way in or out but had to remove from chamber, I also had failure to feeds on a few others that were maybe oversize, I would call them warped, but im pretty new to this world. made it through a box of 50 started on the next. This box shot with no problems, i did have the same issue in both guns, and prior to this have shot over 1000 blazer brass rounds without a problem. again, new to guns, but had a similar problem. this week and today
