      That is simply not true. All you have to do is design your projectile in shape, construction and materials so the kinetic energy gets properly used to have the desired effect on the target.

      A tiny 40 grain .204 Ruger bullet with the insane muzzle velocity of 4100 fps will absolutely explode a watermelon if you use a rapidly expanding projectile such as a ballistic tipped varmint round. If you use the same against a reactive steel target that was only rated for rimfire, it will melt a clean hole through it without even noticeably moving it. And if you use it against a bull moose, it will absolutely destroy a large amount of surface tissue but not achieve enough penetration to reach the internal organs for a clean kill.

      It isn’t a simple problem, the are many different types of dynamics that you can encounter depending on the nature of the projectile, velocity and target.

      Pure theory, likely never ever going to be real, but could a bullet move so fast that it goes through someone without even damaging them?

        Not really applicable but think there could be a small chance it would quantum tunnel through the person but that’s such miniscule chance.
