I guess it's because of the huge difference in weight that we see such a difference in kinetic energy from pellet guns, even though velocity has an exponential impact on the energy. A standard pellet weighs under 14 grains, and a .22 LR bullet weighs 40 grains. Thanks for sharing the formula though. I didn't realize how huge of a contribution velocity makes for kinetic energy, and I'll definitely look for a faster rifle whenever I upgrade my air rifle.
