actually you brought the subject up.....
And who are you to judge others. Have you walked in my shoes? You post some really stupid things even though you call experts liars you know more than they do. I have never nor would consider shooting a deer with a 444 marlin. If it will drop a large black bear or grizzly then its a little big for a deer. Why not a 45-70? Same use...Just too big
" How bullets kill
A rifle bullet kills an animal by destroying tissue, disrupting the function of vital organs or the central nervous system, causing blood loss, and perhaps by shock to the animal's system. The latter can be almost instantly fatal, or almost completely lacking, depending on circumstances beyond the hunter's control. The more damage a bullet causes, the more likely it is to produce a quick kill.
Shock seems most likely to occur when light framed animals are hit by high velocity bullets. The classic case would be when a small (say about 100 pound), relaxed, deer or antelope is hit by a 130 grain .270 bullet at short to medium range. Sometimes the animal goes down so fast that it seems as if the earth was jerked from under its feet. This is the "four feet in the air" effect. But if the same animal were frightened or excited before he was hit, he might run a considerable distance before expiring. As I said, shock can be deadly, but it is unpredictable."- Chuck Hawkes
"How an Arrow Kills
Generally speaking arrows tipped with razor sharp broadheads kill by cutting major blood vessels, both arteries and veins. This causes massive blood loss, reduced blood pressure, and loss of oxygen to the brain. This process is known as hemorrhagic shock. An animal needs to lose about one third of its blood volume for this to happen. This process can take from seconds to several hours depending on where an animal is hit. Another way in which an arrow kills is by puncturing the lungs. Lungs are contained within a pneumatic lining that is airtight and functions like a vacuum allowing the animal to breath. When the lungs are punctured this function is disrupted and the lungs collapse. The collapse of the lungs is known as a pneumo-thorax, and interrupts the exchange of oxygen in blood. When this happens the supply of oxygen to the brain is immediately interrupted and death comes within seconds. A third way that an arrow kills an animal is by cutting through the heart. Hitting the heart also causes death within seconds by stopping blood circulation, and again transport of oxygen to the brain. Since the aiming point on all big game animals is the lung area, most good shots result in a combination of these three factors. If you hit the lungs you will automatically slice through numerous veins and arteries, causing death within seconds. The same goes for a heart shot. "-Chris Eberhart
