Powders (H4350, H4831sc & Rl26) & MV's for 16" 6.5 PRC W/130's-140's?

How many here have 16"-16.5" (Even 17" info appreciated) a 6.5 PRC, shooting 130-140 grain bullets?
With these bullet weights in mind, I am considering H-4350, H-4831sc, and RL 26.
Actual velocities with the brass/powder/bullet combinations you have would be appreciated.
I have all three of the powders listed above.

I like RL-26 best out of a 16" barrel as it'll all burn before leaving the muzzle, the other powder's (as good as they can be) don't. 60.0 grs of RL-26 pushing a Berger 130 AR Hybrid with a COAL of 2.955 gets a velocity at 2794 fps. You're results will likely vary, so run a pressure test in you gun to determine where you should start your load development.

I was thinking R26 would be the secret sauce from the powders I listed-Thank you.
