(49,445 posts)Military ammo is prohibited from being the expanded type by the Hague Treaty of I believe 1896 or 1898. So by law, military ammo can't use hollow-point or soft-nosed bullets.
Countries have gotten around this, to an extent, by making bullets that are prone to tumbling when they hit flesh.
Commercial ammunition, especially for hunting and for self-defense, is designed to mushroom in a controlled fashion. This creates a larger wound channel and dumps more energy and momentum into the target. All of this is to increase the speed and probability of death of whatever it hits, be it a game animal or a violent attacker.
In fact, in most or maybe even all states, expanding ammunition is mandatory for big game hunting. They also generally have minimum power and/or minimum-caliber regulations as well.
