to the more qualified, I have a question. I am reloading for my 300 RUM using remington brass, remington 9 1/2M primers and 99.5 gr Retumbo behind 180 gr interbonds seated at 3.600" so they can be fed through the magazine in my 700 CDL, and still quite far from the lands. The cases are averaging .0002 expansion with the edge of the micrometer head on the shiny rub mark left by my full length resizing die. the primers still look normal to me after firing (much better than the factory loads). After two firings, 20 of 75 primer pockets were so loose that I didn't feel any resistance putting the primer in. I tossed the 20 and am going to reject the other 50 after this firing, but before I finish loading. . . Is this common with the remington brass or did I just get a poor quality batch? How much do you recommend I lower the loads to bring the pressure down during this final firing if that is the problem?
