If a bullet hit a 180 lb target generating 360 fpe. Does the target go over,? I don't think so as looking at police shooting baddies the baddie takes a couple of hits and doesn't go down. What are the physics of this.?
Nope, it took me a while to understand the physics but if the bullet leaving the gun does not have the energy to knock down the person shooting it then actually it does not have the power to actually knock down what it is hitting. The actual 'knock down', if it occurs, will be the body responding to the bullet hitting certain organs and reacting to that.
Opposite but equal reaction? Sounds like the energy is dissipated gradually .Nope, it took me a while to understand the physics but if the bullet leaving the gun does not have the energy to knock down the person shooting it then actually it does not have the power to actually knock down what it is hitting.

Yes, that's a great way to explain it.If you want to visualize the effect, just watch hunting videos (or pay attention while hunting). How often do you see a deer 'knocked of it's feet'? What is the typical reaction? A flinch and several seconds of full out flight before expiring. A deer is approximately same size as a human plus a greater likelihood of a double lung hit and/or broken shoulder with bone shards adding tissue damage.
One should expect no more (and likely far less) terminal performance/effect from a handgun which produces half or less foot pounds of energy on target.
I would argue that a 12ga 00 high velocity buck shot ... within shot gun range would be my definition ! IMHO !"Stopping power is irrelevant because no one has been able to define how much power, force, kinetic energy is needed to quickly stop a determined attacker."
The context was handgun calibers fired in handguns. But I get your point. They have been many shot by a 00 buck that were just injured mainly due to only being hit by 1 or a few pellets and or at range not meant for the shotgun. A full load of 00 buck into a human body is difficult to survive. I know of 1 case that a fleeing robber was hit in the back of his head and died at longer range than normally used for buckshot. About a city block if I remember. That was what bird hunters coined the slang word "magic" pellet. Meaning a single pellet in the head was all that hit the bird and killed it.I would argue that a 12ga 00 high velocity buck shot ... within shot gun range would be my definition ! IMHO !
