This video details an experimental test of a .410 shotgun, '9 Lives,' pushed to its limits with extreme overpressure loads. The firearm, after successfully firing standard .454 Casull rounds, catastrophically failed when subjected to a heavy cast lead projectile with a substantial charge of salvaged powder. Despite the failure, the analysis reveals surprising resilience in certain components and provides valuable data on firearm failure under extreme stress. The instruction comes from Barry of Moss Pond, who possesses extensive shooting experience and proficiency with precision tools.

Quick Summary

The '9 Lives' .410 shotgun failed due to extreme overpressure from a 405gr cast lead projectile and 45 grains of salvaged powder. Despite the catastrophic chamber failure, the firearm's bore remained at .387 inches, and internal mechanisms like the ejector and trigger stayed functional, showing surprising resilience.

Frequently Asked Questions

What caused the '9 Lives' .410 shotgun to fail?

The '9 Lives' .410 shotgun failed due to extreme overpressure. This occurred when firing a 405gr cast lead projectile with 45 grains of salvaged powder, a load far exceeding the firearm's safe operating limits.

What were the key findings after the .410 shotgun's failure?

Post-failure analysis revealed the bore remained at .387 inches, the front sight stayed attached, and critical components like the ejector and trigger remained functional, despite the chamber wall rupturing.

What ammunition was successfully fired before the failure?

Before the catastrophic failure, the .410 shotgun successfully fired five rounds of .454 Casull 300gr Speer Gold Dot ammunition, with the last round reaching a velocity of 1842 FPS.

What is the significance of the bore diameter measurement after the failure?

The bore diameter measurement of .387 inches after the failure is significant because it indicates that the primary damage was localized to the chamber area, and the barrel itself maintained its integrity and dimensions.
