Jaw3- I pretty much go along with what Cayugad is saying. Personally, I am not too much concerned about velocity- to a point. I know increased velocity translates into increased energy (E=MCsquared). For hunting when I reach a rifle/bullet's most accurate combination with an acceptable velocity, that is what I use in that rifle.
Any increase in velocity results in wasted powder, more recoil and reduced accuracy.
Speed is great so long as you have the accompanying accuracy. Otherwise you will just miss your target faster.
But Hey - that's why we play with our rifles. To squeeze every ounce of accuracy we can out of them.
Have fun in your search for the ultimate load.
