The 28 Nosler primer thread got me thinking a bit. Has anybody had first hand experience with standard primers failing in magnum cartridges? I have often found my best loads with either 210M’s or BR2’s in several magnum cartridges. In a picky 28 nosler BR2’s cleaned up ES fairly dramatically. Been loading 210Ms in the 300 WM for several years with no issues. Am I looking for trouble and it just hasn’t happened yet?
