Just saw this and thought you guys and gals at the shoot would like this.
"This is 12 Gauge Flash Bang Ammo. This ammo is manufactured by A.L.S. Technologies, the leader in Less Than Lethal and diversionary ammo. This highly effective diversionary 12 gauge round produces a stun/diversion effect by using a bright blinding flash with an extremely powerful concussion blast from a 12 gauge shotgun muzzle. This device is not restricted by the BATF and is used by prison units and SWAT teams around the world. It produces a 182dB bang, 1.5 to 2 million candlea flash and pressures over 1.5 to 2 atmospheric pressure units. It is truely an awesome experience indoors and out. Hearing protection is required when firing this ammo, it is extremely loud." - Ammunitiontogo.com
