8. .223 caliber rounds are what's used by the military.

The bullet itself is long and skinny. Behind it is a moderately large cartridge shell that tapers outwards, that holds a decent-sized charge of gunpowder.

Compare this with a .22LR, which has a shorter bullet, about the same diameter, but with a much smaller cartridge shell and powder charge.

Don't get me wrong - a .22LR can certainly kill, but it's a relatively weak type of ammunition.

The .223 (what the killer used) is quite a bit more powerful - that big cartridge and powder charge can send that bullet at a very high speed. High speed = long range and high kinetic energy, so those rounds can do a lot of damage when they go through people.
