[QUOTE="MagnumManiac, post: 1480904, member: 10755"] I use mag primers in many standard cartridges, 222, 22-250AI, 6.5-284, 25-06, 338-06 & 45-70. I work up from 5% below max with ALL primer types, if the mag primer shows the tightest group, I run with it. If I were to change to a mag primer in a proven load, I would re-work the test from scratch, there is no hard & fast rule that a reduction in charge weight and working back up to the old velocity will result in the same velocity node. Cheers. :) [/QUOTE]
