How To Get Your Silencer “Hollywood Quiet”

Duration: 10:19

This video explains how to achieve quieter suppressed firearm performance by focusing on four key areas: caliber size matching the suppressor's bore, using subsonic ammunition to eliminate the sonic crack, considering firearms with integrated suppression, and selecting suppressors with larger volumes. It highlights that true 'Hollywood quiet' is most achievable with .22LR, but significant improvements can be made on larger calibers by following these principles.

Quick Summary

To achieve quieter suppressed firearm performance, prioritize subsonic ammunition to eliminate the sonic crack and match the suppressor's bore size to the firearm's caliber. Opting for bolt-action firearms over semi-automatics and selecting suppressors with larger internal volumes also significantly reduces sound.

Frequently Asked Questions

What is the most important factor for making a suppressed firearm quieter?

The most impactful factors for quieter suppressed shooting are using subsonic ammunition to avoid the supersonic crack and matching the suppressor's bore size to the firearm's caliber. Additionally, larger suppressor volume and choosing bolt-action over semi-automatic firearms contribute significantly to sound reduction.

How does ammunition type affect suppressor performance?

Subsonic ammunition is crucial for quiet suppressed shooting because it travels below the speed of sound (typically under 1100 ft/s), preventing the audible 'crack' that supersonic rounds produce. Supersonic ammunition will always have a sonic crack, regardless of the suppressor used.

Are semi-automatic firearms louder than bolt-action firearms when suppressed?

Yes, bolt-action and lever-action firearms are generally quieter when suppressed because their actions do not cycle automatically after each shot. Semi-automatic firearms generate additional noise from the cycling of their actions, which a suppressor cannot fully mitigate.

What is the role of suppressor volume in sound reduction?

Suppressor volume is critical because it provides more space for the expanding propellant gases to dissipate after a shot. A larger internal volume allows these gases to expand more gradually, leading to a significant reduction in the overall sound signature compared to smaller, less voluminous suppressors.
