JB,
Have you tested any of the "newer" RL22?........supposedly not a bad as the "old" stuff.
MM
THAT is interesting, newer RL22?
If that is so, I may have to try some; RL22 used to be my mainstay powder in my 270, 270Wby, and 340Wbys-I got fed up with the velocity swings I would see with changing temps.
