Thread: Federal brass primer pockets??

I have Federal brass in 7mm Rem mag and 223 Rem thats been loaded over 15 times with no primer pocket loosening. Sure it could be a crap batch of brass you have but highly unlikely. Pressure is pressure is pressure. You are overloading, to stretch primer pockets you are well over max. Listen to the other posters here. Saying your not running a hot load wont change things. This is a reocurring theme on this forumn. We have all suffered from the velocity race and ended up destroying brass. All reloading books say approach max loads with caution not go to max and she'll be right.
