Just wanted to give you guys a heads up that some of the "once fired" 338 Norma brass was part of the machine gun trials. I received 120 pieces today and 15 of the cases were jacked. I am pretty sure that it was an FN based belt fed so it may have been feeder claw issues. Regardless, make sure that whoever sells you the brass does a quality control run on it before it ships. If anybody out there has any 338NM brass, let me know.
