.22 калибр мощно выступил, я считаю. на фоне-то.

in essense:

n a certain (fairly high) percentage of shootings, people stop their aggressive actions after being hit with one round regardless of caliber or shot placement. These people are likely NOT physically incapacitated by the bullet. They just don't want to be shot anymore and give up! Call it a psychological stop if you will. Any bullet or caliber combination will likely yield similar results in those cases. And fortunately for us, there are a lot of these "psychological stops" occurring. The problem we have is when we don't get a psychological stop. If our attacker fights through the pain and continues to victimize us, we might want a round that causes the most damage possible. In essence, we are relying on a "physical stop" rather than a "psychological" one. In order to physically force someone to stop their violent actions we need to either hit him in the Central Nervous System (brain or upper spine) or cause enough bleeding that he becomes unconscious. The more powerful rounds look to be better at doing this.

One other factor to consider is that the majority of these shootings did NOT involve shooting through intermediate barriers, cover or heavy clothing. If you anticipate having to do this in your life (i.e. you are a police officer and may have to shoot someone in a car), again, I would lean towards the larger or more powerful rounds.

коротко перевожу: имеется два "останавливающих" фактора: психологический и физический. таблица (набранная статистика) утверждает, что пуля любого калибра имеет высокий шанс вызвать "психологический останавливающий фактор". если же нападающий психически стабилен и желает продолжать атаку через боль, то только смертельное|критическое ранение или достаточная потеря крови вызывает второй фактор. без учета одежды, защиты и прочих препятствий между стволом и целью.
