Can You Tell How Close a Bullet Is by the Sound? | Whizz vs. Crack at 50, 25, 10, and 1 Yard

This video conducts a drywall penetration test comparing various calibers and ammunition types to determine which is "safest" for home defense. The description explicitly states that AR-15s are considered safer than standard 9mm handguns. The video meticulously tests 9mm, 5.56/.223, .308/7.62x51, 300 Blackout, .22LR, .40 S&W, .45 ACP, .410 revolver, and 12 Gauge shotgun loads, providing timestamps for each. Specific bullet types like FMJ, Gold Dot, HST, Frangible, Soft Point, Ballistics Tip, VMAX, M855 Green Tip, and slugs are tested, offering a detailed look at projectile performance through drywall.

Testing subsonic .22LR ammunition with a suppressor reveals a significant reduction in noise compared to standard rounds. While standard .22LR cycles actions perfectly, it remains loud. Subsonic rounds, like CCI Quiet-22, make the bullet impact louder than the shot, demonstrating their effectiveness for suppressed shooting.

This YouTube video explores the differences between supersonic and subsonic 9mm ammunition, posing the question of whether viewers can discern the distinction. The content likely involves firing tests and auditory comparisons to highlight the sonic crack of supersonic rounds versus the quieter nature of subsonic rounds. This type of comparison is valuable for shooters interested in ammunition performance, sound suppression, and the nuances of firearm ballistics.

This YouTube video compares the lethality of subsonic versus supersonic .22LR ammunition. The title directly poses the question of which type is more lethal, indicating a comparative analysis of their terminal ballistics and effectiveness. The content likely explores the physics behind these rounds, potentially including penetration, expansion, and energy transfer, to determine their suitability for various applications where lethality is a primary concern.

This video showcases D3LLC's integrally suppressed firearms, focusing on an H&K MP5SD clone and multiple AR-15 pattern rifles. The demonstration includes a Ruger Mk II, a Remington 700 in .300 AAC, and pistol caliber AR-15s. The description highlights the impressive quietness of these firearms and mentions their use of ported barrels to achieve subsonic speeds for ammunition like 9mm and .22lr. Social media links and an Arfcom discussion thread are provided.

This video features William testing an enhanced Lantac Bolt Carrier Group on a suppressed machine gun. The test utilizes a Dead Air Sandman-K suppressor and involves two different upper receivers: a 10.5" 300BLK and a 16" 5.56. The 5.56 upper is tested with both supersonic and subsonic ammunition, providing a comprehensive evaluation of the BCG's performance under various conditions and with different calibers and ammo types.

This video argues that shotguns are superior to handguns for home defense, demonstrating this through a side-by-side comparison. A single 12-gauge #00 buckshot shell, containing multiple pellets, shows significantly more immediate stopping power than five rounds of 9mm fired from a Glock 17. The visual evidence highlights the dramatic difference in target damage, supporting the claim that shotguns offer greater effectiveness in close-quarters defense scenarios.

This content argues against using a pistol for home defense, favoring shotguns due to their tactical advantages in a defensive scenario. It emphasizes a defensive strategy of holding position and calling 911 rather than actively clearing a home. The video highlights that the perceived length disadvantage of a shotgun is minimal when considering aiming reach in a home environment.

This video demonstrates how to achieve rapid semi-automatic fire on an AK-47 using the bump fire technique, specifically the 'belt loop' method. It clarifies that the rifle remains semi-automatic, with recoil facilitating the rapid trigger reset. The demonstration highlights the effectiveness of this technique for mimicking full-auto fire rates.

This video argues against using a 9mm pistol for home defense, favoring a 12 gauge shotgun. Demonstrations show a 9mm hollow point causing limited damage to a ham target, while a single 12 gauge buckshot round completely obliterates it. Despite similar diameters and velocities between a #00 buckshot pellet and a 9mm round, the shotgun's superior power is evident.
