[QUOTE="just_jon, post: 2868178, member: 112153"] Here you go. My methodology is to use actual cartridge data, run selected powder to max pressure and drop down 3 grains to start load development. Please take note that I used SAAMI case capacity of 84.5 grains and based on COAL and bullet length leaves 72.3 of those grains usable. These are the QL presets for 7 PRC. I would urge you to actually measure water capacity of a sample from your brass. Just insert a spent primer and measure empty and full. If your brass if substantially different, the QL data provided will result in over pressure. For example, recently purchased new Peterson 280AI brass had a case capacity 6% lower than SAAMI and QL preset. I was glad I caught this before pulling the trigger.. If you need anything else, just let me know. As always, start low and work up. I assume no liability for use of this data. Jon [/QUOTE]
