Subsonic Ammo In My Loudest Gun

This guide, presented by a Palmetto State Armory representative, demonstrates the audible and visual differences between supersonic and subsonic 300 Blackout ammunition when fired from a suppressed AR-15. It highlights that subsonic rounds eliminate the sonic crack, offering superior noise reduction for suppressed systems. The principles discussed are applicable to other calibers like 9mm.

This video debunks common firearm myths with practical demonstrations. It clarifies that suppressors do not make firearms silent but significantly reduce noise and recoil. The demonstration shows heavier bullets provide more knockdown power at closer ranges, while lighter, faster bullets with better ballistic coefficients are superior for long-range accuracy. The video also illustrates that barrel length does not inherently dictate accuracy, with caliber and ammunition quality being more critical factors for certain platforms like the 350 Legend. Finally, it concludes that rifle weight (heavy vs. light barrel) has a less significant impact on accuracy than ammunition and barrel quality, especially under varying environmental conditions.

This video explores the effectiveness of the 'Hush Puppy' technique, which involves manually locking the slide to prevent cycling and reduce action noise. The presenter tests this method on a Ruger Mark III, Taurus TX22, and Ruger 10/22, noting a slight reduction in noise, particularly on the Ruger Mark III, when using high-velocity ammunition. The effectiveness is limited by the supersonic crack of the bullet, and the presenter suggests subsonic ammunition would yield better results. The video also touches on the limitations of smartphone decibel meters for accurate firearm sound measurement.

This guide demonstrates the audible difference between supersonic and subsonic 9mm ammunition when used with a suppressor. It highlights how suppressors work by slowing gas expansion and explains that subsonic rounds avoid the 'crack' of breaking the sound barrier. The demonstration involves firing a mixed magazine through a suppressed handgun in an indoor range setting.

This discussion from Regular Guy Training LLC delves into the practical applications and limitations of the 300 Blackout cartridge, particularly in civilian contexts. The panel of firearms instructors and enthusiasts argues that while 300 Blackout was designed for specific military roles, its civilian utility is questionable due to reliability issues, high cost, and a lack of distinct advantages over other calibers. They emphasize that a 'fighting rifle' must be reliable, accurate, and durable, qualities they find lacking in many 300 Blackout platforms when pushed to their limits. The conversation also explores the concept of a Personal Defense Weapon (PDW) and why 300 Blackout often falls short of meeting those requirements.

This video demonstrates the audible difference between supersonic and subsonic 5.7x28mm ammunition when fired from a suppressed firearm outdoors. The speaker highlights the muffled sound of suppressed fire, implying the use of subsonic rounds for maximum noise reduction. Visuals clearly label the two types of ammunition for comparison.

This video presents a humorous skit emphasizing the critical importance of wearing eye protection at the shooting range. It visually demonstrates a handgun malfunction and uses a relatable, albeit exaggerated, scenario with a spent casing to highlight the potential dangers of inadequate eye safety. The creator, experienced in firearm handling and tactical gear, reinforces this essential safety message.

This video features a 'bulletproof' test where a tree is used as a ballistic medium to test various calibers from .22 LR up to .50 BMG. The Civilian Tactical host, demonstrating high-level firearms expertise, shows that even powerful rounds like .50 BMG can be significantly stopped by a dense tree, with none of the tested rounds achieving a complete pass-through. The test highlights the surprising terminal ballistics of different ammunition types against natural barriers.

This video from Civilian Tactical explores the concept of using a human body, simulated with ballistic gel, as a suppressor. The host fires a Derya Arms .22 rifle directly against a ballistic gel head and block, noting the shot sounded 'dead silent.' The experiment demonstrates the penetration depth of a .22 LR round through the simulated head and into the gel block.

This video demonstrates a ballistic test on a Belgian M1 steel helmet, evaluating its resistance against various calibers from birdshot to .223. The test, conducted by Civilian Tactical Host, shows that the helmet is not bulletproof against common handgun and rifle rounds like 9mm and .223. The host's energetic and demonstration-oriented style, coupled with expertise in tactical gear, provides a clear assessment of the helmet's limitations.
