[QUOTE="Buffalobob, post: 79984, member: 8"] What you are describing is why the open ocean fisheries have been depleted by the commercial fishing operations. The high tech approach is simply devastating the fish populations in every ocean in the world. Anyway back to pdogs. Somewhere in my computer I made some conservation of momentum calculations. Momentum is just the mass of the object multiplied times the veleocity of the object. A varmint bullet at high speed has a momentum of about 1.0 - 1.5. A prairie dog weighs about one pound so if you disintergrate you varmint bullet on him /or her the momentum is transferred to the pdog which then moves with a velocity of 1.0 to 1.5 feet per second. If you shoot low and hit it low then the moementum is applied a distance of about six inches (assuming the dog is 12 inches high) from the center of mass. This gives you a torque arm of six inches. Torque is angular momentum., This causes the pdog to fly and rotate. Now then if you shoot a hundred pound deer with the same bullet you give the deer the same momentum of 1.0 so to get the speed at which the deer is slammed to the ground you must divide 1.0 by 100 pounds and you get a velocity of the deer of 0.01 fps - it moves one foot every one hundred seconds. For a 1000 pound moose of bufffalo you would impart a speed of 0.001 fps (i.e. he would not even twitch). In all of this nonsense is the simple fact that a 55 grain varmint bullet will move a pdog wieghing one pound but if you want to move a deer weighing 100 pounds you would need to shoot a bullet weighing 100 times more - 5,500 gr bullet traveling at a speed of about 3500 fps. This would flip a deer over like a pdog. I believe this is about a 105 howitzer. I suspect you already know most of this but maybe some of the kids can learn something about the difference between bullet energy and bullet momentum. [/QUOTE]
