Abstract: On October 16, 2006, Employee #1 was working for a retail store at which firearms were sold. A coworker had received a Black Diamond .50 caliber inline style muzzleloader at the counter. The customer indicated that it had been double loaded. There were three pellets of Pyrodex, a saboted slug, another three pellets of Pyrodex, and another slug on top of all that in the muzzle. The coworker tried without success to remove the top bullet by using a bullet puller, but the polymer tip in the bullet was too hard to drive the bullet puller into. He then asked Employee #1 to attempt to clear the double load. During this attempt, the weapon discharged, and Employee #1 sustained injuries to his hand or finger. Employee #2, who was just entering the area, received a metal fragment in his eye. Neither Employee #1 nor Employee #2 was hospitalized. It was determined that neither employee who worked on the gun (the coworker and Employee #1) used water or solvent to deactivate the Pyrodex.
