This can be used in handguns and rifles. Its advantage lays essentially its small weight and optimized volume.
Case-less Cartridge/Ammo
50
It is more sensitive to moisture and shocks compared to cased ammo. It cannot be adapted for use in revolvers because the chamber of the cylinder of the revolver is smooth from side to side and it’s the case that holds the round.
