I've been shooting a long while now, and for range use I love Tulammo because its cheap, it's fairly accurate, and it's been reliable up until two weeks ago. I was helping some friends and new shooters with some training when I had a FTE in my AR. It turned out to be a weak rim on a Tulammo .223 that broke when the bolt tried extracting the round. Then yesterday I had the exact thing happen again. I can't be positive, but I believe the rounds were from two different batches. Has anyone experienced this before? I contacted Tulammo USA yesterday, sent them a message on there web site. If anyone is interested ill post a response if/when I get one.
