I know IMI has had issues from time to time, you would have to do a google search as to lot numbers.
Have you guys had issues with IMI ammo?
The only 223/556 ammunition I have ever had issues with was NATEC PCA Spectrum. A polymer and brass case. A great new idea. A horrible idea. The plastic part of the case would consistently separate from the brass part. The brass would be ejected from the rifle and the plastic would stay lodged in the chamber. I will include a few pictures to show exactly what happens. This stuff isn't produced anymore and was a total failure but I have seen some floating around on gunbroker from time to time. Stay away from it. I am glad I only purchased 2 boxes. I saw a guy purchasing an entire case of the stuff at a gunshow years ago and tried to warn him. He didn't listen and probably thought I wanted it for myself or something. He will learn.
Anyone have problems with Geco?
