dont think for a minute hornady will let flaws slide i made a suggestion to hornady through a personal friend and darn good bulder when i heard they would be making 404 and 426 brass that they might want to temper the brass to weatherby spec as a had had a grat deal of trouble with some wildcat based on 404 cases and the 416 which operate at much pressure this could possibly be the problem that the brass is harder than you have experienced sure might keep primer pockets from getting lose i will say this though i have not had that problenwith the hornady brass before call them they will tyell you what to do and fix the problem pronto you can bet on it
