UZI Feed Problem

[FMF]

I took My new UZI out yesterday to fire fore the first time , I used Win White Box 115 gr FMJ , it ran great for the most part , but about every 50 rounds the front ege of the case would catch something and bend back slightly and fail to chamber I would then be unable to use that round , is this common ? or is there something I can do ? , thanks , Dave B
