StaBall is in the 4350 burn rate. I’ve seen higher velocities than I expected. RL16 is great, but Bean & I haven’t been able to get the velocity we want/expect out of it.My wild guess of reloading powder lingo means too slow
I use RL16 with the 124 in my 6.5 Creed. Single digit ES, sub 0.5 moa, and 3033 fps.
