The amount of ft/lbs of energy will not increase. The total force available is exactly what it was at muzzle. Mass times velocity. Now if you wanted to say that focusing the force that would be spread over a ft of space subjected to a d
Aller frontal area, subjects that small area to greater relative force, you may be able to get there mathematically, but it won't still be ft/lbs at that point. However the total energy that the projectile of a given mass at a given velocity does not change. That's why we stick with a common measurement. And the total ft/lbs is what is being discussed.

Even if a bullet has the total ft/lbs of energy available, it may not expend it all in a target. Especially a target that is three dimensional, with variations of fluid levels, density, and hardened surfaces throughout. Any energy remaining after the projectile passes through is not transferred to the target, and can be considered wasted.

The mistake on the math is that you are trying to find energy by multiplying velocity times energy. So you are squaring the energy. To get energy you need to multiply velocity times mass.

Fernando- don't be snide- your math is flawed. Energy is speed squared times mass. I'm not a math teacher but I am an engineer.

In terminal ballistics there are several variables- weight, speed, cross section of the projectile, and where it strikes and route that it takes on entering body are SOME of them.

As far as the 9mm Parabellum being a bad choice- while there others that may be a better choice, it is not a bad choice. That round has been in use for over 100 years, and has been a military handgun, carbine and SMG round for major armies.

Me? I do not want to get shot with a BB gun.

Some people have survived 12 gauge or 7.62 rounds, and some have died from .380's. Some people survive horrible car wrecks, some die in much kess violent ones... The point? I don't know, I guess the point is you never really know. What do you think?
I just say no to thinkin much these days

There's lot's of real-life parallels to this ballistic comparison.

Case in point- one guy gets a shock from a light socket,

falls over dead. Another guy, takes thousands of volts

from a power station, and survives, none the worse for the wear.

Somebody else gets killed jumping their car, but another guy

survives multiple lightning strikes.

Agreed. I usually carry a Glock 21SF but sometimes carry a .380 or .38 for easier concealment.
