.223 cartridge (.223rem)

This cartridge is a rifle cartridge, available in both the sports variant and hunting calibers.
So you can use it perfectly on the shooting range during a practice day with your shooting club or during hunting.
They are available in various types on the market.
For example: Full metal jacket, Soft points, jacketed hollow points.
They also call a .223 cartridge the commercial cartridge of the 5.56Nato, but this is not correct
this seems to be the same cartridge.
However, the shape of the cartridge is different, resulting in a greater pressure charge due to the close fit in the chamber upon firing.
So it can do massive damage to use a 5.56 cartridge in a weapon made for a .223 cartridge.
