Those air rifles can do more than that. In the .457 build, the marketing says the muzzle energy can reach 450 ft-lbs. Non +P 9mm has ~350 ft-lbs of muzzle energy. Even the overpressured 9mm rounds are only slightly higher than the .457. I'm pretty sure one of those could kill a human.

This has me curious what muzzle energy is actually measuring. ft-lbs is usually a unit of torque, but I don't think there's any rotation in a relevant direction here?

  See https://en.wikipedia.org/wiki/Foot-pound_(energy) https://en.wikipedia.org/wiki/Foot-pound_(energy) - it's both a possible torque measurement and a energy measurement. Just like miles per hour can be a speed or a battery recharging measurement.

    Ah, linear displacement, of course. Customary units, bleh :) I'm incredibly glad there was no metric/customary split in electricity.

      Every vacuum/most electric motors being rated in horsepower rears its head ;)
