Just posting this here for a general FYI, I've picked up some Federal/Lake City 5.56mm because it was fresh clean ammunition at a great price and the previous LC ammunition I have purchased has had increased case capacity compared to the civilian cases, and has been lasting me longer than other stuff. However it appears that LC is switching primer crimp techniques. In one of the boxes of this ammunition there is some remarkably heavy stab crimping. (Talking four incisions) As opposed to the normal roll circular crimp. I recently ended 7 and a half years in the Army, with two deployments under my belt and of all the 5.56mm ammunition I have seen, This is the first time I have seen stab crimping used. The only time I've seen stab crimping has been on the .50 cal stuff. (Also, while I know this stuff is military seconds, released to the civilian market it is odd to see two different crimp styles in one box of ammunition. I've not opened the other two boxes, yet) While this may not adversely affect me as I have a Dillion Crimp remover, it may affect others out there so I thought I would let you all know what I observed.
