I have only used RL-15 for this bullet weight in the 9.3x62. I am not near my notes now but if memory serves me correct I started at 60 gr and stopped at 64 gr. Velocity was a bit over 2600 fps out of a 20 inch barrel with the 64 gr load and excellent accuracy. As always, start low and work up watching for pressure signs.
