[QUOTE="Mike Matteson, post: 2307515, member: 101791"] I generally don't use mag primers, but generally use longer barrel lengths and up 75 grains. Mag primers there noting wrong with them, and I feel that mag primers are needed with shorter barrel lengths with slower powders. My rifles I use Fed 210 primers. Reduce your loads some and do a run on increased powder charge to see where high pressure signs show up. With shortage of primers, and powder that won't use to many rounds to find that out. Generally the run up of powder charge can be done in 1/2gr increases. I look over every fired case for high press signs. [/QUOTE]
