Re: Sorry if this Starts another Argument
Ok, let me take a stab at this one. The deputy is right about what he says about knockdown power in that the force is equal on the bullet on both ends; however, on the shooter's side the force of the bullet is opposed by the weight of the gun. Also, the bearing surface area of the stock distributes the force remaining after the opposition of the weight of the gun onto the shoulder and forehand gripping the stock if shot standing. This is why shooting standing had some what less recoil than shooting from the bench.
Now I believe in knockdown power, but because no two animals are the same or shot the same, too many variables like the naimals state of alertness/stress...Let me site two examples of Moose the same size and shot with the same rifle and bullet at the same distances with the same aiming point:
#1. Broadside shot @ 150 yards with a 338 Win mag 250 gr Seirra boatail. The moose was knocked over and his feet actually came up in the air and then fell down. He was dead when he hit the ground. After skinning it I found about 3/4 of the bullet in several fragments embeded on the off side. I wonder how much energy it takes to do this to a 250 gr Sierra? It would be some, but all the energy was contained in the moose about 3500 foot pounds.
#2. I shot the moose and he kept walking about 3 ro 4 steps and then sat down!? I fired again at the same spot. He just sat there in the same spot 150 yards away with his head up!!!I nearly paniced. then I caught myself and thought that a moose wouldn't just sit there after being shot at twice. So I reloaded and waited a minutes or so with out him moving. When I got to him there was a piece of wood I couldn't see that was under his head holding it up. My two shots were about 1/2" apart and neither had hit a rib. Both bullets had passed through the animal cleanly and there was very nearly zero meat damage.
In both cases the heart was missed, but was lying loose unconected by veins or arteries in the chest cavity. It seems the first animal absorbed more erngy from the first bullet, all of it. The second since both passed through only a % of each bullet's energy. The second one kept walking after being hit like he was on a Sunday stroll. While the first was knocked over so hard his feet came up into the air. As I stated I believe in knockdown power, but I think these examples shows it can be very hard to accurately define.
