ok you are right your not going to knock them off their feet you could take a shot gun blast to the chest at point blank standing on one foot. You are correct sir. Lets call it....."i dont want to play anymore power"...Fair enough?.....Though i still say...shot to the groin breaks the pelvis therfore making it impossible to stand...and...knocking the person down. Again you are right...no movie type getting blown across the room stuff.
Sorry, I wasn't clear enough.
The term "knock down power" is a gun magazine/Hollywood term. It just doesn't exist. It's kind of like "Assault Weapons". Bullets don't knock people over, not bullets fired from normal guns anyway. It's more of a semantic argument, I know, but I hate the Hollywood butchering of all this stuff.
What you are referring to is "stopping power". The ability to stop the target... in other words, disable, put it down, etc etc. Is a 12 gauge burst of buckshot more powerful? HELL YEAH!
I do like "I don't want to play anymore power" though!

I think I'll adopt that term.
