[QUOTE="Pdvdh, post: 249005, member: 4191"] I found that the non-magnum primers yield lower extreme spreads and standard deviations in fps velocity. Don't use a magnum primer with my 74.9 gr powder charge without working up to it cautiously, as it will likely be one fiesty load. Regarding the non-magnum primers, I've experienced the same thing with my 300 Win Mag. When you drop down to the standard large rifle primers you may see a decrease in MV and then have to increase the powder charge a tad to get back up to your maximum charge. [/QUOTE]
