There has been an inquiry that has been requested maybe over a century. Will a shot fired into the back of a live cartridge set it off? FullMag chose to attempt this urban myth out for himself. With a live .50 BMG cartridge secured as an objective he lines up the shot with a .50 BMG rifle. The monstrous shot pushes through the back of the cartridge case and continues going in a rush. The shot in the focused on cartridge never departs the packaging. For this situation the live cartridge did not discharge when the shot hits it in the rear. This myth may have been part completely open for this situation.
