[QUOTE="Greyfox, post: 523356, member: 10291"] I have definitely seen differences in performance between primers, even within the same classification ie. Large rifle. I have a Rem 308 Milspec 308 that shoots best with standard Win LR primers with IMR 4895. Tried other LR's, and Match primers, double checked with my chronograph and confirmed with velocity spread. If the goal was 1 MOA, no difference would be seen but combo gave consistent .25-.5moa. Precision Shooter Magazine had a study a couple of years ago that measured the flash intensity produced by different primers and you could clearly see differences. The bench rest guys at my club are fanatics about this and buy there primers in 5000 ct. of the same lot. [/QUOTE]
