How Do Blanks Work As Compared to Regular Bullets?
By Mark Mancini
To understand how blanks work, and how they are different from real bullets, first we must clarify the difference between a bullet and a cartridge—two terms that are often confused. A bullet is the piece of a cartridge that flies forward in order to strike a target. Here’s a helpful illustration:
The gray lump that’s labeled 1 is the bullet. Typically, these contain a lead core that’s enveloped in a harder metallic case. Bullets poke out from the top of a shell (2), which also houses gunpowder (3) or a similar substance.
Now, look at the shell’s bottom. Down there, you’ll find both a rim (4) and a primer (5). When the gun’s trigger is pulled, a firing pin strikes the primer, causing the powder to ignite. As it burns, it rapidly releases gasses that build up with enough force to launch the bullet out of the cartridge and through the gun barrel.
In contrast, blank cartridges work by doing away with metal bullets altogether. Instead, the top of the shell is crimped or covered with a wad of paper, plastic, felt, or cotton. (The wadding or crimping prevents gunpowder from spilling out.) Fire a blank, and you’ll still get that convincing gunshot noise. Because there is no bullet to be propelled as a result of the explosion, these special cartridges aren’t likely to injure anyone—unless, of course, they’re used improperly.
Make no mistake: blanks can kill. In 1984, actor Jon Erik-Hexum died while on the set of CBS’s Cover-Up as a result of a blank cartridge. Bored by incessant delays, the actor pointed a gun loaded with blanks to his head and reportedly said, “Can you believe this crap?” before pulling the trigger.
He had pressed the barrel directly to his temple, and the force of the explosion still did incredible damage, even without a bullet. It drove a small chunk of his own skull into his brain, which caused severe hemorrhaging and put him in a coma. He died as a result of his injuries.
“Blanks aren’t toys,” warns firearms dealer Bob Lesmeister. “You have to remember that the force of the exploding gas is great enough to fire a bullet.” In fact, some blank cartridges contain more gunpowder than regular ones in order to ensure an extra-loud sound.
Jon Erik-Hexum's death wasn’t an isolated incident. Blank cartridges have been responsible for multiple reported fatalities. As with all forms of ammunition, caution must be exercised when dealing with these rounds.
