[QUOTE="Pdvdh, post: 1397789, member: 4191"] This much is for certain. You're overpressuring the case heads of your brass beyond its yield strain limit. Either got $hitty weak brass or your running above normal maximum load pressure. Why you had one primer pocket blow wide open, 0.050" oversized, is up to you to figure out. I lost a primer in Hornady 375 Ruger casing recently. But my primer pocket didn't open up 0.050" oversized. My primer pocket ID measured 0.215" and the primer OD measured 0.212" after firing this cartridge, which allowed the primer to fall free of the case head upon ejection of the Hornady case from the chamber. I'm done with Hornady brass. Now using RWS, and possibly Norma. Hornady is too inconsistent in case head strength, in my opinion. [/QUOTE]
