The VOG-25 family of low-velocity grenade rounds is intended for use in udner-barrel and stand-alone grenade launchers developed in USSR and Russia. These rounds are unique because the propelling charge is located at the base of the projectile, so after its launch there’s no fired case in the barrel. All rounds are loaded from the muzzle, and the family includes HE-FRAG, Illuminating, thermobaric, smoke and gas-dispensing loads.
Typical round of VOG-25 family weights around 250-300 gram and has muzzle velocity of 76 m/s. For standard HE-FRAG VOG-25 round lethal radius of its framments is about 6-9 meters.
