In the midst of the hunting season for ungulates. Someone has managed to go hunting and come back with a trophy worthy and someone went several times and came back with nothing. And not because of bad luck. It often happens: you went to the beast you took careful aim, shot, hit, and the beast was gone. This means that the shot not what you need. Here are a few examples from the past seasons.

Hunter from the tower from a distance of 50–70 m shooting a wild boar. Weapons – carbine «Elk» (chuck 7,62h51). The bullet gets wild boar in the chest and the animal weight 130–150 kg remains on the site. Arrow left only to come up and control shot to end the agony of the animal.
The next hunt with me to a nearby room jumped pig weighing 40–50 kg. The hunter fired at him from a carbine caliber 9,3×64 within 30–50 m. The bullet hit the back of the animal’s thigh. There was a squeal of a pig, and then all was quiet. I can not say how much he ran, but after being hit by a bullet far left. Now imagine how much time you would have chased him, getting it into him with a gun? And at 9.3 mm bullet hit the animal died on the spot just in shock.
Recently I had a chance to talk to one hunter, having armed with a carbine caliber 8h68. Asked about the results of the hunt, he said that any animal, including bears (which he got about 15 heads), lies on the ground from getting a bullet in any part of the body.

Another example. Again with me to the adjacent room opens hog weight and 40–50 kg. The hunter, armed with a shotgun 12 gauge, the first bullet shot from 20 meters–30, carries literally lumps lungs, the second bullet on the flight passes beast breaking in its path exactly in the middle of the heart.
After such injuries, in general, a small hog ran another 50 meters Now imagine that you are in a large bulls or bears. Yes, they are a hundred times torn heart will have time to devour you. Kill animals such in situ is possible only once in the brain, head or spinal cord. But this is not always possible.
So what better to shoot large animals? Now for me the answer is obvious – Only threaded chuck. I want to understand why this is happening. It seems that caliber rifles have considerably more weight bullets too. It’s all in the other.

Stop and the damaging effect of bullets piled up, firstly, of the energy transmitted by the animal’s body, and secondly, from the expansive properties of bullets. Gushing effects bullets for rifles are significantly higher than those for the smooth-bore bullets. Lead slug fired from a smooth barrel, almost destroyed, knocking the animal carcass.
Exceptions are special bullets expansive action. However, ordinary hunters, they are rarely used. Wound channel from a bullet, maybe more than the bullet fired from the rifle (although this is a controversial issue), but it affects only a small area around it. But even the smallest soft point bullet (I mean bullet caliber 7.62 and above, for hunting large animals should be used only half-shell) gives the diameter of the cross section of the wound up to 50 cm in diameter, in fact nashinkovyvaya him with shrapnel.
Consider the second component – the energy of the bullet. We calculate it by well-known formula: E = MV2 / 2. We take a lot of bullets shotgun ’30 flight speed of about 400 m / s. We get energy – 4800 J. Now Calculate the energy of the bullets for rifles. The standard weight of a bullet about 9 multiply by the square of flight velocity (900 m / s). We get the energy equal to 7290 J.

It turns out that the energy transferred by the lightest almost bullet body of the animal, more than 1.5 times greater than the energy of a bullet for the shotgun. And if you shoot 8 or 9 mm ammunition, bullets energy is still several times more. And the possibility to return home with the trophy will also be several times higher. I’m not saying that bullets fired from rifles, often penetrate right through even such large animals like elk, taking with them a large part of the energy.
Immediately say, that these calculations are made for hunting rifles. Carbines, developed on the basis of military-style, have a significantly lower speed flight bullets. Have boasted «Tiger» Muzzle velocity is not 900, and 700 m / s. But, my friends, we must not hunt with military weapons and the hunting. Dragunov sniper rifle created yet to defeat a person weighing 80–100 kg, not a moose or a bear.
