How Quiet Can You Make A Gunshot???

This guide details an experimental technique for extreme sound suppression of firearms, as demonstrated by Matt Carriker of Demolition Ranch. It involves using a moving blanket and even burying a suppressed rifle in dirt to achieve maximum noise reduction. The video highlights the effectiveness of subsonic ammunition and the inherent quietness of bolt-action platforms compared to semi-automatics. Expert insights into NFA regulations and practical application of sound dampening are provided.

Quick Summary

Extreme sound suppression can be achieved by using a moving blanket to dampen noise or, in experimental tests, by burying a suppressed firearm in dirt. Bolt-action rifles are inherently quieter than semi-automatics when suppressed. Subsonic ammunition is key to eliminating the supersonic "crack" for maximum quietness.

Frequently Asked Questions

How can you make a suppressed gunshot quieter?

You can further reduce the sound of a suppressed gunshot by wrapping the firearm in sound-dampening materials like a moving blanket. For extreme reduction, burying the suppressed firearm in dirt has been tested, though it carries risks of damage.

What is the difference in sound between bolt-action and semi-automatic suppressed rifles?

Bolt-action rifles are generally quieter when suppressed because they lack the cycling action of a semi-automatic. This means there's no reciprocating mass or gas expulsion from the action itself, contributing to a lower overall sound signature.

What are the risks of using unconventional methods for sound suppression?

Unconventional methods like burying a suppressed firearm in dirt can lead to significant damage. Risks include baffle strikes from debris, obstruction of the suppressor's ports, and ingress of dirt and moisture, potentially rendering the suppressor useless or dangerous.

What role does subsonic ammunition play in sound suppression?

Subsonic ammunition travels below the speed of sound, eliminating the loud "crack" that accompanies supersonic bullets. This makes it a crucial component for achieving effective sound suppression with a suppressor, as it removes the primary sonic boom.
