This video demonstrates a potentially dangerous 'life hack' for using a 12-gauge shotgun shell in a standard flare gun for emergency signaling. It emphasizes that a full shell will not work and could cause the flare gun to explode due to a safety lip. The correct method involves removing the shot, powder, and wad, leaving only the primer to create a loud bang for signaling.

Quick Summary

A standard 12-gauge shotgun shell cannot be fired from a flare gun due to internal safety lips. Attempting to do so risks explosion. The safe signaling method involves removing the shot, powder, and wad, leaving only the primer to create a loud bang.

Frequently Asked Questions

Can I fire a regular 12-gauge shotgun shell from a flare gun?

No, a standard 12-gauge shotgun shell will not fully seat in a flare gun due to a safety lip. Attempting to fire it can cause the flare gun to explode. The safe method involves removing the shot, powder, and wad.

What is the safe way to use a 12-gauge shell for signaling with a flare gun?

The safe method is to completely disassemble the 12-gauge shell, removing the shot, powder, and plastic wad. Only the primer should remain, which will create a loud bang when fired in the flare gun for signaling purposes.

Why is the plastic wad dangerous in a flare gun modification?

The plastic wad and cup from a 12-gauge shell are too large for a flare gun's barrel. If not removed, they can cause catastrophic pressure buildup when fired, potentially destroying the flare gun and causing injury.

How loud is a flare gun modified for signaling?

When modified correctly by removing all components except the primer, a 12-gauge shell fired from a flare gun produces a loud bang, reportedly louder than a .22LR firearm. This is effective for emergency signaling.
