[QUOTE="Greyfox, post: 1264439, member: 10291"] Checking my records for my load development and shooting sessions for my rifles I might have discovered a possible cause. For several years I have recorded temperature, wind, velocity, etc. After checking my records I wonder if primer choice/ignition could be playing a role with the problems some are experiencing. With my 6.5x284's that use 58gr of Retumbo I found about five years ago that when using Fed215M's, groups were still excellent and I would get velocities which were generally higher by 30-50FPS compared to Fed210M's, but, would increase another 30-50FPS with higher ES in colder temperatures. For that reason I settled on Fed210M's. This has not occured at all with the Fed210M's which have proven to produce consistent velocities and low ES over a wide temperature range since. [/QUOTE]
