[QUOTE="cajun, post: 2908363, member: 9772"] Case head separations are the result of too much headspace or over sizing. They don’t just happen. There’s a reason no go gauges are used to chamber barrels. If you dont make a false shoulder most belted mags will stretch 10-15 thou on the first firing. If you keep head spacing on the belt this is what happens. I’m not preaching. It happened to me as well before I knew any better. I measure every case with a comparator now before sizing. [/QUOTE]
