Percussion Revolvers in the Rain

Published on August 18, 2021
Duration: 20:01

This video tests the reliability of percussion revolvers and flintlocks in simulated heavy rain. While percussion systems offer an improvement over flintlocks, both proved highly unreliable in wet conditions, with frequent misfires due to water contamination of the ignition source. The tests highlight the limitations of these designs and the historical necessity for metallic cartridges.

Quick Summary

Percussion revolvers like the Colt 1860 Army and Starr Single Action proved highly unreliable in simulated heavy rain, experiencing frequent misfires. Moisture contamination of the percussion caps is the primary failure point, rendering the ignition system ineffective and highlighting the need for more robust designs like metallic cartridges.

Frequently Asked Questions

How reliable are percussion revolvers in the rain?

Percussion revolvers, including models like the Colt 1860 Army and Starr Single Action, proved highly unreliable in simulated heavy rain during testing. They experienced frequent misfires, requiring multiple hammer strikes to achieve ignition, demonstrating significant vulnerability to moisture.

Why did the flintlock pistol fail in the rain test?

The flintlock pistol failed immediately after simulated rain was applied because the water contaminated the priming powder in the pan, turning it into mud. This prevented the spark from igniting the main charge, rendering the firearm inoperable.

What is the primary failure point for percussion revolvers in wet conditions?

The primary failure point for percussion revolvers in wet conditions appears to be the percussion cap and nipple interface. Moisture can penetrate the cap, preventing detonation or significantly delaying ignition, even if the seal at the front of the cylinder is adequate.

Did using wads improve percussion revolver reliability in rain?

No, testing with wads placed between the powder and the ball showed no significant improvement in the reliability of percussion revolvers during the rain test. This suggests that the issue lies primarily with the ignition system's susceptibility to moisture, not powder containment.
