The Solothurn 20mm Anti-Tank Rifle

The Lahti L-39 20mm anti-tank rifle, nicknamed 'Miss Lottie,' is a historical firearm chambered in 20x138mmB, boasting immense power with over 35,000 ft-lbs of muzzle energy, nearly triple that of a .50 BMG. This semi-automatic rifle features a unique top-loading 10-round magazine, a robust charging crank system, and a massive muzzle brake. Its design includes sleds for snow transport that double as a bipod, significantly improving stability and reducing recoil during firing.

This video showcases the immense power of the Solothurn 20mm Anti-Tank Rifle by testing its penetration capabilities against advanced ballistic protection. The rifle, weighing over 120 lbs and firing a 2,330-grain projectile, effortlessly defeated a Level IV ballistic helmet, a Level IV body armor plate, and even a combination of a ballistic shield and armor. The demonstration highlights the sheer destructive potential of large-caliber anti-materiel rifles.

This review details the improvements made to the Boys Anti-Tank Rifle between the Mk I and Mk I* variants. Key upgrades include a simplified and more effective muzzle brake, a streamlined rear sight, and a more stable bipod design, all aimed at reducing manufacturing costs and improving usability. The video also touches on historical context, effectiveness against early tanks, and production markings related to Lend-Lease.

This video demonstrates a critical loading failure with the Swiss 20mm S18-1000 anti-tank rifle. The operator experiences an auto-eject magazine malfunction upon cycling the action, highlighting a potential reliability issue with this specific firearm configuration. The instructor's casual reaction and acknowledgment of the 'fail' suggest a familiarity with heavy weaponry and a focus on practical, albeit sometimes humorous, firearm handling.

This review of the Boys Mk I Anti-Tank Rifle highlights its unique recoil mitigation system, where the upper receiver recoils into the frame. The .55 Boys cartridge is detailed, including its standard and tungsten-core variants, and the effectiveness of the 'cookie cutter' muzzle brake is demonstrated. Legal implications in the US regarding its .50 caliber classification as a destructive device are also discussed.

The Boys Anti-Tank Rifle, a .55 caliber bolt-action rifle, was developed by the British between the World Wars. Initially intended to counter early tanks, its effectiveness diminished as armor improved. The rifle's role shifted to anti-materiel, and it was famously used by US Marines, including during the Makin Raid. Soldier confidence was boosted by propaganda films, and many civilian-owned examples are now re-chambered in .50 BMG.

This video details a catastrophic failure of a Serbu RN-50 rifle chambered in .50 BMG, which exploded due to extreme pressure exceeding 85,000 PSI. The incident resulted in severe injuries to the shooter, Scott, including a broken orbital bone, nose, lacerated jugular vein, and punctured lung. The analysis points to the breech cap shearing off its threads as the failure point, highlighting the dangers of exceeding firearm pressure limits.

This video from Kentucky Ballistics puts the Desert Eagle Mark XIX through a series of extreme environmental torture tests. The firearm demonstrates impressive initial resilience, functioning perfectly after water submersion and snow exposure. However, it encounters significant malfunctions when subjected to mud and sand, highlighting potential failure points in extreme conditions. The test is conducted by Scott, a recognized authority in destructive firearm testing.

This video features a series of extreme caliber tests using a zombie torso dummy. The .700 Nitro Express is tested with a 1000-grain soft point round, followed by .600, .500, and .470 Nitro Express calibers. Additional tests include the .460 Weatherby Magnum and .500 Jeffery, showcasing the immense power and recoil of these large-bore firearms.

This Liberty Safe National Classic Select underwent extreme torture tests, including a flamethrower fire simulation and ballistic impacts. While it withstood .45 ACP, .50 AE, .500 S&W Magnum, and .450 Marlin rounds, a .308 Win round penetrated, and .50 BMG rounds easily breached the safe. Despite significant damage, the safe's frame remained intact against mechanical force.
