- In comparisons of ammunition, the energy not the momentum is
- usually tabulated, and many state hunting laws require a
- minimum bullet energy (to avoid wounding instead of killing game.)
- I think it's energy not momentum that would reflect the damage a
- bullet does.
-
- As for spreading out the energy over a greater area, that certainly
- helps, but the real question is over how large an area? A punch
- delivers on the order of 50 ft-lbs spread out over the area of the
- fist. That's about a tenth the energy of a pistol bullet. Even if the
- vest distributes the bullet's energy over a similar area, it would
- still be an order of magnitude worse than a punch. Since punches
- occasionally result in broken bones, I'd think a bullet stopped by
- a bullet-proof vest has a reasonable chance of doing the same.
