11mm Devisme Cartridge Revolver

The Gevelot 11mm sliding-chamber pinfire rifle, patented in 1866, was a unique design intended to rival the French Chassepot. It featured a novel sliding chamber mechanism and a cartridge bridging paper and metallic rounds. Despite its innovative design, it never saw military adoption and remains exceptionally rare, with only a few known examples surviving.

The Colette Gravity Pistol, patented between 1850-1854, is a unique 11mm sporting pistol that utilizes a gravity-fed mechanism for its 20-round capacity. It fires caseless 'rocket ball' cartridges, making it a low-noise, low-recoil firearm ideal for recreational shooting. The pistol's design, developed by Herman Jean Nicholas and manufactured by Colette, relies on tilting the muzzle to load cartridges into the breech.

This review delves into the Allen & Wheelock Lipfire Navy Revolver, highlighting its historical context within 19th-century patent disputes, particularly the Rollin White patent. The video details the unique lipfire cartridge and the innovative rack and pinion ejection system. It also touches upon the revolver's mechanical operation and its eventual conversion to standard rimfire ammunition.

This review delves into the rare System Kuhn single-shot breech-loading rifle from the 1870s/1880s. It highlights the rifle's unique two-trigger system for operation and safety, automatic case ejection, and robust internal mechanism. The analysis covers its 11mm black powder caliber, adjustable target sights, and origin from Besançon, France, suggesting a sporting or target shooting purpose.

This review of the Mle 1866 Chassepot highlights its unique needle-fire bolt action and caseless paper cartridges. Despite significant black powder fouling that stiffens the action, the rifle remains functional for its intended engagement lengths. The manageable recoil and historical significance make it a fascinating piece for firearms enthusiasts.

The German Mauser 71/84 is Germany's first repeating rifle, featuring a Kropatschek tubular magazine that holds eight 11mm cartridges. Despite its historical significance, its nearly 51-inch length and over 10-pound weight make it cumbersome. It produces significant smoke and recoil due to its black powder operation and large bullet, and was quickly surpassed by smokeless powder designs.

This video details the unique 'French Finger Trap' issue with the MAS-36 rifle's bayonet, where two rifles can become unintentionally locked together. A 1951 French arsenal memorandum identified this problem, proposing a simple modification to the bayonet handle. Drilling a small hole allows a tool, like a firing pin, to depress the internal spring, enabling the separation of locked rifles.

The M134 Minigun is a scaled-down 7.62 NATO rotary cannon, requiring 24V DC power and consuming 1.5 kW. Its high rate of fire (3,000+ RPM) is essential for aircraft engagement windows. The complex delinker mechanism is critical for feeding ammunition, and practical hand-held use is impossible due to weight and recoil. Live fire demonstrates rapid ammunition consumption and the need for indirect aiming.

The H&K G11 is a revolutionary prototype assault rifle designed in the late 20th century, notable for its caseless ammunition and unique rotating drum bolt mechanism. Despite advanced features like a 2000 RPM burst fire rate and integrated optics, its development was ultimately halted by geopolitical shifts and cost concerns.

This video demonstrates the assembly and live-fire of the German 1936 pattern light mortar (L.Gr.W.36). It highlights the mortar's leveling mechanism for accuracy and the difficulty in visually tracking its 50mm projectiles after firing. The content showcases historical military hardware and its operational use.
