Lucky gunner labs has some relatively new data on these calibers.
I was struck by the relatively small differences in performance in the gelatin regarding penetration and expansion.
I wish they would put ft/lbs of force instead of just simple muzzle velocity since it makes more sense regarding "how hard it hits".
I think this calculator is helpful because it allows comparison of multiple loads.

I also plugged the formula into an excel spreadsheet so you can put as many bullet weights and velocities in as you want. just enter the weight and velocity in columns A and B and copy the formula in C2 and past it all the way down. I guess the forum won't allow upload of excel so here is a screenshot of how I set it up.
Oh yeah, and ballistics by the inch can help extrapolate to longer barrel lenghts...
