i switched to useing mag primer in the middle of loading for the 220. i noticed no decrease in acuracy. maybe noticed better acuracy but i was useing difrent primer and powder so no teln though the groups did shoot very tight that 40grs of h380 and the 55vmax in the 220.
figured what the hey id use the mag primers in the 2506 pushn the same powder and bullets as i was with the reg primers.
groups are printing very good.
so far i see no reason to change. guess youd have to shoot my rifle with my reloads to know. theres only so much chaberin i can do then it start to be just jabeering.
eitherway i see no advantage or dissadvantag to mag primers in either 220 or 2506.
and neither of these have mag printed after the caliber.
what if these same calibers were labeld 220mag 2506 rem mag
i thik then mag primers would be used left and right by almost all that reloaded for them.

ps
i thought the same as you. i skeptical and alittle lerry of switching to mag primers figured my acruacy would decrease or i might see pressure signs sooner.
found nothing of the like. but did find some very tight groups and no pressure signs at max loads.
