OP
Sorry I skipped over this, caught it while re-reading the thread. I'm using CCI BR-2 large rifle primers in the 6.5 CM. I have a box that's kinda old that I bought second hand from someone a couple years back that I'm burning through. I also have another box of 1000 that I just bought. I don't know if they degrade over time but I plan to pay attention when I bust into the new box to see if there's any changes. In the 6 ARC I'm using Fed GM205MAR small rifle.
