OneStrike with its compressed tungsten powder metal core is designed to 1- give faster, massive fragmentation in soft tissue. 2- fragment apart as it passes through light barriers such as interior walls, windows. Some barriers OneStrike will not over penetrate such as airplane seats and aircraft hulls. OneStrike is ideal for high crowd areas such as schools, hospitals, and VIP events. It is also excellent for use in guarding nuclear facilities, refineries, or sensitive areas where an over penetration through a structure could spell disaster. One Strike is the round to use inside your house to stop a threat. If a miss occurs, the core’s frangible characteristics cause the bullet to start fragmenting as it passes through the first wall, rapidly dispersing the bullet’s energy so it doesn’t go through multiple walls.
