Prototype .45 Caliber Roth-Krnka for US and UK Trials

This video explores the Schouboe Prototype .45 Pistols, notably those that competed in the 1907 US Army pistol trials. Designed by Jens Schouboe, also known for the Madsen machine gun, these pistols featured a simple blowback design chambered in .45 caliber. They utilized a unique, lightweight, high-velocity cartridge (63 grains at 1600fps) which led to their rejection by the Army, who favored the .45 ACP cartridge. The video highlights the pistols' remarkably simple disassembly. Two examples are shown: a standard version with metal grips and a fancy gold-inlaid model intended for the President of Uruguay.

This video compares two iconic revolvers: the Colt Single Action Army and the Colt Walker, both chambered in .45 Colt. The title indicates a direct 'showdown,' suggesting an in-depth evaluation of their performance, historical significance, and perhaps practical differences for modern shooters. The description is currently unavailable but the title itself provides enough information to anticipate a focus on these classic .45 caliber handguns.

This review showcases .45 ACP HEI (High Explosive Incendiary) rounds from Firequest, demonstrating their potent explosive and incendiary effects on steel targets. The video features a Palmetto State Armory handgun with a Holosun optic, highlighting the dramatic visual impact of these specialized rounds. The demonstration emphasizes the significant energy release upon impact.

The Austro-Hungarian Roth-Krnka M.7 Pistol is a unique striker-fired, short-recoil handgun firing the 8mm Roth-Steyr cartridge. It features a 10-round capacity loaded via stripper clip and a heavy trigger that partially cocks the action, negating the need for a manual safety. Despite its innovative design for the era, the M.7 is described as feeling somewhat 'underbaked' with potential yet to be fully realized.

This video provides a practical guide to loading Pyrodex Pistol Pellets into a Remington New Model Army .44 caliber revolver. Dustin Winegar, demonstrating high technical proficiency, details the process of inserting pellets and seating .454 round balls, emphasizing careful handling to avoid pellet damage. The review includes live-fire chronograph data, showing an average velocity of 1069.3 FPS with a tight 10 FPS spread when outliers are excluded, highlighting the consistency of the Pyrodex pellets when loaded correctly.

The Barnekov Greene Prototype 1870 carbine represents a unique open-bolt, toggle-locked single-shot rifle design that competed in the 1872 US Army trials. Despite its innovative mechanism, the design suffered from accuracy issues due to the open-bolt operation and potential safety concerns, leading to its withdrawal. This rare prototype, patented by K.L. Barnekov, ultimately did not see adoption, remaining a historical curiosity.

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.
