@Beavis assuming you will be using 140 grain bullets so I will give you the data for that, let us know if you want the data for 120 grain bullets
COAL = 3.00"
Test barrel = Kreiger 24"
Primer = CCI200
Case = RP
2209
(H4350) start 38.0 = 2444 FPS
Max 40.0 = 2531 FPS
RL22
Start 43.0 = 2579 FPS
Max 45.0 = 2655 FPS
Sierra data for RL22 & 140 grain bullets
Start = 37.7 = 2300FPS
Max = 45.7 = 2700 fps
Looks like the RL22 might be the best bet which has the best velocity gain compared to the other listed powders
Attention: owners with military actions this data is for commercial actions only DO NOT try it in your ex military actioned rifles.
