Temperature stability of CFE223
#2
My 123 Amax load is 31.2grs of CFE at 2.250. As you know, CFE is a bit temperature sensitive. Here are average velocities take on different days out of a 22" barrel at various temps. Measured at the muzzle. As you can see it's all over the map but the trend is upward really spikes over 80 degrees. I'm not confident in those 90 degree numbers. I really need to re-shoot that sometime.

2497 40 degrees
2504 40
2506 45
2540 56
2544 50
2548 53
2561 68
2561 60
2580 75
2583 75
2608 80
2661 90
2674 90

Did government credibility die of Covid or with Covid?
