RL-17 won't give you velocity gains in every application. But to say it won't in all applications is poppycock!
I've loaded it in the 6.5 Creedmoor and had a safe load at over 2900 with the 140. My load with H4350 runs just under 2800.
With the 200 gr Accubond in the .30-06, you will see similar gains.
I will also tell you that the velocity gains come at a price; there is no free lunch. The price is shorter barrel life. I've experienced that too
