Testing The Bullet That Killed Osama Bin Laden

This video from Guns Blazing Ranch features a direct comparison between an AK-47 (7.62x39mm) and an M16A1 (5.56x45mm) in a concrete penetration test. The AK-47's heavier 7.62x39mm round demonstrated more explosive fragmentation, while the M16A1's 5.56x45mm round caused the concrete block to split into larger pieces. The demonstration highlights the distinct terminal ballistics of each caliber.

This video provides a direct comparison of .300 Blackout and 5.56 NATO energy output out to 75 yards, using two 16-inch barrel AR-15 platforms and specific handloads. The analysis, conducted by The Gun Dungeon Host, utilizes a LabRadar to measure velocity and calculate energy, concluding that .300 Blackout offers significantly more energy at these distances, making it a strong contender for deer hunting where a minimum of 1000 ft-lbs is often recommended.

Sootch00 provides an enthusiastic review of the next-generation FN SCAR rifles, highlighting a dramatically improved shooter experience. Both the SCAR 17S and SCAR 16S are praised for their exceptionally smooth and soft shooting characteristics, with the reviewer noting remarkable accuracy even when shooting standing. The modularity of the new generation is also a key point, allowing existing owners to upgrade their current SCARs.

This review of the HK MR556-A4 after 6,000 rounds, conducted by Regular Guy Training LLC, highlights exceptional reliability with zero malfunctions across diverse ammunition and magazine types. The piston-driven system requires minimal cleaning, making it practical for serious use. While heavy and expensive, the rifle delivers on its promise of high-end performance and reliability, as assessed by an experienced instructor who used it in training classes.

This video provides a direct comparison between the PSA AK-P (5.56) and the Zastava M85 (7.62), highlighting their physical similarities and key differences. The host, demonstrating experienced shooter insights, expresses a strong preference for the Zastava M85 due to its exceptionally flat shooting characteristics, particularly when suppressed, despite potential aftermarket furniture limitations. Viewers are encouraged to consider their caliber preference when choosing between these AK variants.

Garand Thumb's expert analysis debunks myths about 5.56x45mm NATO lethality from short barrels. The video demonstrates through rigorous testing with high-speed cameras and ballistics gel that 5.56 remains highly effective at close to moderate ranges (up to 125 yards) even from barrels as short as 10.3 inches. Both M855 and Hornady BTHP rounds show significant fragmentation and energy transfer, proving their suitability for home defense and tactical scenarios.

This video rigorously tests the self-defense capabilities of various airguns against a realistic human head ballistic target. The expert instructor demonstrates that low-power BB guns like the Daisy Red Rider offer minimal threat, while even full-auto CO2 BB guns fail to penetrate the skull. However, a high-velocity Gamo pellet rifle proves capable of causing significant damage, cracking the skull. The instructor concludes that BB guns are unsuitable for self-defense, and while pellet rifles are dangerous, they lack the immediate stopping power of conventional firearms.

This video tests the BulletSafe VP3 Level IIIA vest against various calibers up to .44 Magnum using a realistic human torso dummy. While the vest stopped all tested rounds, including a .44 Magnum and 12-gauge buckshot, significant backface deformation and blunt force trauma were evident, especially with higher-energy rounds. The dummy's shoulder blade was broken by buckshot, and severe bruising was indicated by the .44 Magnum impact.

This review of the Crosman DPMS SBR full-auto BB gun highlights its realistic AR-15 SBR aesthetics and select-fire capability. The host demonstrates its operation, including loading with a speedloader and the dual CO2 power system. Performance metrics like 1400 RPM and 430 FPS are discussed, along with its accuracy and destructive potential on targets like watermelons. The device is recommended for realistic training or plinking where live firearms are impractical.

This video tests the effectiveness and dangers of using a flare gun for self-defense. While a flare gun can ignite materials and cause internal damage to a ballistic torso, its single-shot capacity, slow reload, and high risk of starting fires make it an irresponsible and dangerous choice for defense. The test highlights the unpredictable nature and significant fire hazard associated with using flare guns in a defensive scenario.
