[QUOTE="flashhole, post: 872511, member: 21375"] I load for 7mm Rem Mag. The powder column in a 7mm RM is large. A magnum primer is designed to be aggressive and send the ignition flame deep into the powder column for uniform ignition of the powder. A uniform pressure front is good for accuracy. All of the "Magnum" primers I've used with 7RM have worked well and I really can't say I had any notable difference in performance between brands. That said, my choice is Winchester Large Rifle Magnum Primers when I can find them. I really like Retumbo with heavy for caliber bullets. H-1000 was a disappointment in the 7RM, accuracy sucked.
