Supersonic vs Subsonic

This guide, based on Hickok45's demonstration, explains how to maximize suppressor effectiveness. It highlights the critical difference between supersonic and subsonic ammunition, showing how subsonic rounds significantly reduce the audible report by eliminating the sonic boom. The video emphasizes that for the quietest shooting experience, ammunition velocity must be below the speed of sound.

Quick Summary

To maximize suppressor performance, use subsonic ammunition. Unlike supersonic rounds that create an audible sonic boom, subsonic ammunition travels below the speed of sound, eliminating this crack. This results in a significantly quieter shot, where the primary sound is the bullet impacting the target, as demonstrated by Hickok45 with the Banish 30 Gold suppressor.

Frequently Asked Questions

What is the main difference between supersonic and subsonic ammunition when using a suppressor?

Supersonic ammunition travels faster than the speed of sound, creating an audible 'crack' or sonic boom even with a suppressor. Subsonic ammunition travels below the speed of sound, eliminating this crack and making the shot significantly quieter, with the bullet impact being the primary audible sound.

How can I get the most out of my firearm suppressor?

To maximize your suppressor's effectiveness, it's crucial to use subsonic ammunition. This type of ammunition travels below the speed of sound, preventing the audible sonic boom that significantly diminishes the sound-dampening capabilities of the suppressor.

What is the Banish 30 Gold suppressor?

The Banish 30 Gold is a modular suppressor, as demonstrated by Hickok45. It can be configured to different lengths (7-inch or 9-inch) and is rated to handle calibers up to .300 RUM, offering versatility for various rifle platforms.

Why is ammunition velocity important for suppressors?

Ammunition velocity is critical because it determines whether the bullet breaks the sound barrier. Supersonic rounds create a sonic boom, which is a major noise component that even suppressors cannot fully eliminate. Subsonic rounds avoid this, allowing the suppressor to focus on muffling the muzzle blast.
