Out of my 26" 6.5PRC I was loading 59.5grs of Re#25 with Rem 9 1/2 LRP and getting bug holes and average velocity of 3,3030 pushing 140gr ELDs . Then started using Fed 210 Match primers behind 59grs of Re#25 and I averaged 100 FPS faster and same bug hole groups.Are fed primers the hottest primers out there ?

That's funny, I was using 9 1/2 primers then switched to 210m. When I switched to 210m, my MV dropped by 50-75.
Hmmm??? With which powder?
With 6.5 Creedmoor... Everything I had been using 9 1/2 primers with. BLc2, R17, H4350 at that point.
So, some significant difference in powder being used where R25 is a slower burning powder than R17. Aside from other factors that can be involved, the different results between the two of you switching from the 9 1/5 to 210M is interesting.
I have no history with a Rem primer of any kind, but anytime I had swapped between a CCI 200 and a 210M, the CCI always produced more speed, all else equal. So IMO 210M not a hot primer.
I just had to post, even though I brought nothing to the table, lol
The only thing that enters my mind is are you getting a better burn of your powder, and the only way to figure this out would be a cleanliness test, are 210M loads cleaner(barrel)
