An ejected 9mm shell casing struck a live round in a partially open ammo box, causing an accidental discharge. While extremely rare due to primer design, this incident highlights the kinetic energy of ejected brass. Colion Noir advises keeping ammo boxes closed on the range to prevent such hazards.

Quick Summary

An ejected 9mm shell casing struck a live round's primer in a partially open ammo box, causing an accidental discharge. While rare due to recessed primers, this highlights the kinetic energy of brass. Keep ammo boxes closed on the range to prevent such hazards.

Frequently Asked Questions

Can ejected brass cause a live round to fire?

Yes, though extremely rare, an ejected shell casing can strike a live round's primer with enough force and precision to cause an accidental discharge, as demonstrated in a viral video analyzed by Colion Noir.

What safety features prevent ammo from discharging accidentally?

Ammunition primers are often recessed to prevent ignition from drops or surface impacts. However, a direct, forceful impact on the primer's center, like from ejected brass, can still cause a discharge.

Why is it important to keep ammo boxes closed on the range?

Keeping ammo boxes closed prevents stray ejected brass, which carries significant heat and kinetic energy, from striking live rounds inside and potentially causing an accidental discharge or other safety issues.

What are the dangers of an 'out-of-battery' discharge?

An out-of-battery discharge occurs without a barrel to contain pressure. While often less lethal due to casing velocity, it remains a significant hazard and can cause firearm damage or injury.
