OK, I've been wondering how the idea of 'knock down power' came into the popular venacular?
Basic physics tells us that all the energy in a bullet's acceleration in a barrel must be exerted equally on the gun (and thus the shooter.) There is then also the additional reactive force of the ejecting gases (acting like a rocket engine) that occur after the bullet has left the barrel and on it's merry way.
So, any 'knock down power' any particuliar human-mount-fired projectile posseseses must be visited upon the shooter at least equally, if not in greater magnitude.
Infact, it is only the added mass of the gun (which just lowers the velocity of the impulse, and somewhat in concert with the stock, legenthens the interval in which it is presented as a force.) and the wider area of the butt-stock that prevents a gun from being driven into the shooter's shoulder.
So how can a round be said to have much of a 'knock down power' type effect? (incapacatative effects, which with CNS hits can be devistating, notwithstanding.)
