Lost Arts Part 5: The Little .410 Shotgun that Could

Published on January 9, 2012
Duration: 5:54

This video details an experimental test of a Brazilian-made .410 shotgun, pushing its limits with high-pressure rifle cartridges like the .30-30 Winchester, .444 Marlin, and .454 Casull. The hosts, demonstrating high expertise, use precision tools like micrometers to assess the firearm's structural integrity after firing rounds far exceeding its intended caliber and pressure ratings. The results highlight the surprising durability of this inexpensive import.

Quick Summary

An experimental test pushed a Brazilian .410 shotgun to its limits using high-pressure rifle rounds (.30-30 Win, .444 Marlin, .454 Casull). Despite extreme stress, the firearm showed surprising durability, with no structural failure, perfectly ejected brass, and unchanged bore dimensions measured by micrometer.

Frequently Asked Questions

What happened when a .30-30 Winchester round was fired from the .410 shotgun?

When a .30-30 Winchester round was fired from the .410 shotgun, it lacked power, performing similarly to a .22 LR. The brass casing split significantly due to inadequate chamber support, though the shotgun itself remained undamaged.

How did the .454 Casull round affect the .410 shotgun?

The .454 Casull round, with its high pressure of approximately 55,000 PSI, completely destroyed the water jug targets. Post-firing inspection showed the shotgun's action still functioned, brass ejected perfectly, and the bore diameter remained unchanged, indicating no structural failure.

What is the significance of the .410 shotgun lacking a serial number?

The absence of a serial number on the Brazilian-made .410 shotgun suggests it was likely imported into the US before 1968, as federal law requiring serial numbers on firearms was enacted around that time.

What tools were used to assess the .410 shotgun's condition after extreme testing?

After firing high-pressure rifle rounds, the hosts used a micrometer to measure the shotgun's bore diameter, ensuring it had not expanded or deformed under the extreme stress.
