Right, but not by much. The .40 S&W has only a very little more energy, and in some loadings, it has less.
- According to this source, 5.7x28 --
- 32 gr FMJ -- 397 ft-lb
- 40 gr JHP -- 340 ft-lb
- According to published specifications for Federal Ammunition, .40 S&W --
- 165 gr Hydra-Shok -- 352 ft-lb
- 180 gr Hydra-Shok -- 400 ft-lb

Lets say we have 2 cartridges. 1 has 500 ftlbs and uses 400 of those effectively to create damage. 2 has 800 ftlbs and uses 500 of those effectively to create damage. Assuming that damage is done to equivalent areas of the target, cartridges 2 is less efficient but more effective.

But since it this is made up, it really doesn't mean anything. And how do you come up with this sort of notion? Do you have any evidence to support this conjecture? Can you cite any authority to support it. As the experts I quoted in post 52 point out, the energy doesn't create the damage.
Your fundamental premise is fallacious.
