Loading a shotgun with a 50bmg, will it work?

This guide details the experimental process of firing a .50 BMG round from a 12-gauge pump-action shotgun, as demonstrated by Edwin Sarkissian. It covers the loading procedure, remote firing technique for safety, and analysis of the results, including casing expansion and projectile performance. The experiment concludes that while possible, this is highly inefficient and impractical due to significant energy loss and lack of accuracy.

Quick Summary

Firing a .50 BMG round from a 12-gauge shotgun is physically possible but highly inefficient and impractical. The 12-gauge chamber expands to fit the larger casing, losing propellant energy, and the smoothbore barrel fails to stabilize the projectile, resulting in poor accuracy and effectiveness.

Frequently Asked Questions

Can you fire a .50 BMG round from a 12-gauge shotgun?

Yes, it is physically possible to load and fire a .50 BMG round from a 12-gauge shotgun. However, as demonstrated by Edwin Sarkissian, this is highly inefficient and impractical due to significant energy loss and poor projectile stabilization from the smoothbore barrel.

What happens when you fire a .50 BMG from a 12-gauge shotgun?

When a .50 BMG is fired from a 12-gauge shotgun, the shotgun's chamber expands to fit the larger casing, leading to a loss of propellant energy. The smoothbore barrel also fails to stabilize the projectile, resulting in reduced accuracy and effectiveness compared to firing from its intended platform.

Why is firing a .50 BMG from a 12-gauge shotgun inefficient?

It's inefficient because the 12-gauge chamber is not designed for the .50 BMG cartridge, causing the casing to expand excessively and bleed off propellant gas. Additionally, the smoothbore barrel of a typical shotgun does not impart the necessary spin for aerodynamic stability of the .50 BMG projectile.

What was the observed effect of firing a .50 BMG from a 12-gauge shotgun?

The experiment showed significant damage to concrete blocks but less than expected. Analysis revealed the .50 BMG projectile's jacket peeled, and observed fire was from unburnt gunpowder, not the incendiary tip, due to casing expansion and lack of stabilization.
