Big Joe,
Right now, and probably for quite a while into the future, there is no absolute way to measure any round's power. You have Taylor's KO values, and the standard energy equation ((mv^2)/c), but I don't like either one of them too well for one simple reason. No one has been able to take into account the shape of the bullet nose, and therefore accurately depict how much energy will be transferred to the target. For example, a pointed FMJ is will not have near the energy transfer of a hollow point, wadcutter, or round-nosed bullet. This is also why a lot of "ballistically inferior" cartridges do extremely well in the field (the 30-30 for one). Even though many people have tried to come up with an absolute formula, there is probably no way to account for the different shapes of the bullets, velocity, weight, B.C., etc. in one formula. It's not a bad ideal to look at these things before selecting a caliber/cartridge, but it doesn't mean too much in the field. That's my 2 cents worth. LOL
