This is a 2 part exploding target. Open the target and empty the included plastic bag into the target. Shake for 30 seconds or until well mixed. Shoot the target with a "rifle round" with a velocity of 2300 feet per second or faster, such as 223, 762×39, 308, 762x54R, 30-06 50 BMG ETC ETC. We recommend the use of FMJ type ammo. Maintain the minimum distance of 100 yards when you detonate the target. The explosion will sound like a stick of dynamite blowing up, but is not a fire hazard.
