The 4 BORE Rifle (The Biggest Rifle EVER !!!)

This video from Forgotten Weapons, hosted by Ian McCollum, clearly explains the fundamental differences between a firearm's operating system and its locking system. The locking system ensures the breech is sealed during firing, while the operating system manages the cycling of the action for reloading. McCollum uses historical examples like the Luger P08 and Martini-Henry to illustrate various mechanical principles.

This video tests various firearms against a custom ballistic torso simulating Wolverine's adamantium skeleton. Smaller calibers like .22 LR, 5.7x28mm, 9mm, and .45 ACP failed to penetrate the metal structure. Larger handgun calibers like 10mm and .50 GI also proved ineffective. However, powerful magnum handgun rounds (.50 AE, .500 S&W) and rifle calibers (.30-06, .416 Rigby) caused significant damage, with the 4 Bore and a safe drop completely destroying the torso.

This video pits Houston Jones against extreme recoil from a series of progressively larger caliber big-bore rifles, culminating in the massive 4 Bore. The challenge highlights the physical toll of handling such powerful firearms, with Jones experiencing increasing discomfort. The video showcases rare and powerful rifles, emphasizing their unique calibers and the significant felt recoil associated with them.

This video provides a historical overview of the Martini-Henry rifle, detailing its development from earlier designs like the Peabody and Snyder conversions. It highlights the rifle's service with the British military, particularly its iconic role during the Zulu War and at Rorke's Drift. The discussion covers the evolution of the Martini-Henry through its various marks (Mark I to Mark IV), including changes in action refinement and caliber, culminating in the 40 caliber Mark IV.

This guide breaks down the fundamental differences between a firearm's operating system and its locking system, crucial for understanding how firearms function. It uses examples like the Martini-Henry and FN Model 1903 to illustrate these concepts, emphasizing that the operating system cycles the action while the locking system ensures breech safety during firing. Expert Ian McCollum highlights that these systems can vary independently, leading to diverse firearm designs.

This video details a catastrophic failure of a Serbu RN-50 rifle chambered in .50 BMG, resulting in severe injuries to the shooter, Scott from Kentucky Ballistics. The incident highlights extreme pressure events and the critical importance of firearm safety and immediate medical response. Scott's resilience and commitment to educating viewers despite his injuries are evident.

This video details a comprehensive torture test of the Desert Eagle Mark XIX, conducted by Scott from Kentucky Ballistics. The firearm was subjected to extreme conditions including water submersion, snow burial, mud immersion, and sand burial. Despite some malfunctions in mud and sand, the Desert Eagle demonstrated notable resilience, functioning after water and snow exposure. The test highlights the firearm's robust construction and the importance of understanding its limitations under adverse conditions.

This video tests the myth of water being bulletproof by firing various firearms, from 9mm handguns to a .50 BMG rifle, into a water tank. Results show that even high-powered rounds like the .50 BMG are significantly slowed or stopped by water, failing to penetrate to the target. The tests demonstrate water's effectiveness in dissipating projectile energy.

This video features Scott from Kentucky Ballistics testing several of the world's largest caliber firearms against a realistic ballistic dummy torso. The expert demonstrates the destructive power of rounds like the .700 Nitro Express (1000 grain) and .600 Nitro Express (900 grain), showcasing detailed firearm engravings and unique actions like the Blaser R8 straight-pull bolt. The testing provides valuable insights into the performance of these extreme hunting calibers on simulated organic material.
