Energy, pressure, momentum, and shot placement all matter, and there is no direct comparison on all of these things between a bullet and a sling stone.
Most likely you are right. But I saw a video on YouTube of the police firing 12 shots at a suspect who resisted, 10 of those shots hit him and he survived. A firearm has negligible momentum compared to a sling. And in fact, not only is there no direct comparison between a sling and firearms, but in general, in principle, nothing can be directly compared, I think so. And speaking of energy in joules, Pistol Makarov, PM, caliber 9mm 9x18
bullet weight 5.54 - 5.8 grammes
bullet speed 315 meters per second, have energy 297.675 Joules
maximum 300 - 320 Joules.
one kilogram of bullet stopping action.
a prime example of when a firearm fails in theory.
But no practice.
In sling with stone 100 grammes flies speed 30 meters per second have 6 kilogram stopping action.
And 90 Joules energy
