Why does the military use FMJ ammo?
The use of full metal jacketing in military ammunition came about in part because of the need for improved feeding characteristics in small arms that used internal mechanical manipulation of the cartridge in order to chamber rounds as opposed to externally hand-reloading single-shot firearms.
Can Ball ammo be used for self defense?
In short, ball ammo has no place in a defensive handgun aside from target shooting at the range. You should always carry quality, proven hollow point bullets. The worst problem a quality hollow point can have is that it fails to expand, in which case it is just like having used ball ammo in the first place.
Is full metal jacket ammo for target shooting?

Can you carry FMJ for self-defense?

Is it OK to use FMJ for self defense?
This expansion creates a wound cavity and will also slow the round down so that it’s likely not to continue beyond your target with much force, if it makes it out at all. One of the most dangerous things that can happen if using FMJ for self defense, is hitting another person that happens to be beyond your target.
Is FMJ fine for self-defense?
Self Defence: FMJ ammo is not often used in self-defense situations due to the risk of the bullet striking an unintended target. It is a small-arms projectile, it can be used in concealed carry guns. Hollow point bullets are better for shoot to kill and self-defense situations.

Is FMJ illegal?
FMJ ammunition was designed in the late 1800s for use in military rifles. Not long after this, the Hague Convention of 1899 made it illegal to use bullets that easily expand or flatten inside the body. Interestingly enough, the United States did not sign off on this.
