[QUOTE="J E Custom, post: 1916003, member: 2736"] Most powders used in the volume range of the 308 based cases don't need a magnum primer and will generally get better results with the large rifle primer. Magnum primers may give you slightly more velocity, but along with that comes more pressure. I would recommend trying different standard large rifle primers to get the best SD,s and accuracy. Magnum primers are not the go to primers in many cartridges and even some of the magnum cartridges. In some rifle cartridge combinations, LR primers perform better/More accurate than Magnum primers. Huge cartridges with copious amounts of slow burning powder need magnum primers and should use them, but small cartridges with less than 65 to 70 grain capacity can/will often benefit from standard rifle primers. Magnum primers will work fine in small capacity cartridges but other than having trouble finding load data that uses magnum primers (For the reasons discussed) you might be missing out on some fantastic accuracy by using them. Try some standard rifle primers and then switch brands to find out which gives the best accuracy. I have foung the best SD's and accuracy using the CCI BR 2 in the 260, 260 AI, 7/08, 7/08 AI and the 308 Win using the powders I prefer for these cartridges. J E CUSTOM [/QUOTE]
