Immediately stop shooting if you hear any time of pop while using your firearm.

Glenn Fleming said you may have what's called a squib round, which can happen with both reloads or factory ammunition.

"Basically its a round that has no powder in it, and when you hit the primer, the primer pushes the bullet itself into the barrel and it lodges there," Fleming said.

Continuing to shoot can be very dangerous as "it can blow up your gun," Fleming said. "If you go to reload and you don't know what to do, don't reload."
