Sinclair International has a helpful, three-part video series on Full-Length Sizing. The full-length sizing die performs multiple important functions: it resizes the case body, resizes the neck, and adjusts the headspace relative to the chamber (it can also eject the spent primer if that was not...bulletin.accurateshooter.com
I get that I’m overly focused on just this one point. A magnum is headspaced belt to bolt face, so the firing pin/ejector doesn’t push it forward until the shoulder touches, usually. In a normal headspace gun, the belt should touch first with new ammo.However, in my own experience, I haven't so much run the tests to match up one method against another, its just that I learned the hard way you CANNOT full length size belted magnum cartridges past 2-3 times without head case failures. At least I could not. I had 6-7 head case failures on my .300 win mag. which of course is a belted magnum.
