This guide details the experimental process of firing a modified .50 BMG round from a 12-gauge shotgun. It covers the necessary ammunition modification, secure firearm mounting for remote firing, and the use of water-filled buckets as a ballistic medium. The analysis includes the fire-forming of the .50 BMG brass to 12-gauge dimensions and observations on powder burn rate. The video strongly emphasizes the extreme danger and advises against attempting this experiment.

Quick Summary

Firing a modified .50 BMG round from a 12-gauge shotgun involves taping the .50 BMG case for chamber fitment and remotely firing the shotgun mounted in a vise. The experiment revealed slow powder burn and fire-formed brass, with a strong warning against attempting this dangerous procedure.

Frequently Asked Questions

How was the .50 BMG round modified to fit a 12-gauge shotgun?

The .50 BMG round was modified by applying red tape around its base. This tape helped to ensure a snug fit and support the cartridge within the 12-gauge shotgun's chamber, compensating for the dimensional differences.

What safety measures were taken during this dangerous experiment?

Extreme safety precautions were implemented, including mounting the shotgun in a gun vise for stability and using a string for remote firing. This allowed the operators to discharge the firearm from a significant distance, minimizing risk.

What was observed about the gunpowder after firing?

A substantial amount of unburnt gunpowder granules were found embedded in the water buckets and lids. This indicated that the .50 BMG powder's burn rate was too slow for the 12-gauge shotgun's barrel length, leading to inefficient combustion.

What happened to the .50 BMG casing after being fired from the 12-gauge shotgun?

The .50 BMG brass casing underwent significant fire-forming. It expanded to precisely match the dimensions of the 12-gauge shotgun chamber, demonstrating the immense pressure involved in the firing process.
