All I can tell you is I was exactly Noslers load 22 load with 23 and 63.0 with 22 with 140's.
I've had a couple guns that no matter how much powder I put in the case it wouldn't go anywhere. Example was a 338Wm with a 210NP and RL19 wouldnt go any faster than 2800 then when I switched to IMR 4350 it shot lights out at 2950. Another one was my 20BRA H4350 and RL16 wouldnt go anywhere either untill I switched to RL15
