 The main event of the Machine Gun Shoot is the "Night shoot" where, after dark, gasoline-filled metal drums and explosives are set up in and around the targets, and tracer ammunition is used.Although reserving a lane for the machine gun shoot is difficult with a several-years-long waiting list, lane holders usually rent the use of their weapons to spectators for a nominal fee to cover the cost of ammunition and wear and tear on the guns themselves.The Military Gun Show is also a place for dealers to buy, sell and trade Class III firearms.
