What is a squib?

• A. A round with primer but no powder
• B. A round with a reduced powder charge
• C. A misfire due to hang fire
• D. A type of bullet

Answer: (A)

A squib is when the primer fires but little or no propellant is available to push the bullet. With no powder (or effectively none), the bullet’s energy is so low that it may not exit the barrel at all, leaving a bullet effectively stuck in the bore. That’s why this option—the round that has a primer but no powder—best fits the definition. If you compare the others, a reduced powder charge means there’s still some propellant and the bullet might move, just more slowly; a hang fire is a delay between primer ignition and powder ignition, not the same as having no powder at all; and a type of bullet is unrelated to the malfunction described. Squibs are dangerous because firing another round into a bore that still contains a lodged bullet can cause a catastrophic barrel failure. If you suspect one, stop firing and inspect the bore before proceeding.
