[QUOTE="BryanLitz, post: 280996, member: 7848"] Hodgdon's powders are well known for being insensitive to temperature. I'd be surprised if you could measure a significant difference in average velocity over a 50-60 degree temperature difference. Regarding primers; Back when I shot 7mm Rem Mag, I struggled a lot with MV variation until I tried standard (non-magnum) primers. As I recall, the average MV wasn't much different, and the variation went way down. I've heard others observe this too. -Bryan [/QUOTE]
