This test compares subsonic and supersonic .22LR ammunition lethality using Clear Ballistics gelatin and a cloth barrier. Results indicate that heavy subsonic FMJ rounds can penetrate beyond the FBI's 12-inch minimum, challenging the assumption that they are less deadly than supersonic hollow points. The supersonic hollow point demonstrated expected mushrooming.

This video delves into the history and specifics of the Finnish m/91 pienoiskivääri, a .22 rimfire Mosin Nagant trainer rifle. Developed in the 1920s by the Finnish Defense Forces for cost-effective marksmanship training, these rifles featured barrels converted using the Salerno process or new barrels from Tikkakoski. The video explains their production numbers, their use during World War II, and their eventual sale as surplus. It highlights their scarcity in the United States due to not being sold in bulk to major importers.

This review from Cranky Gun Reviews provides a direct accuracy comparison between the Walther P22Q and the Ruger SR22P chambered in .22LR. The reviewer, demonstrating intermediate skill, found the Ruger SR22P to be highly accurate, placing shots consistently in the bullseye. While the Walther P22Q was deemed 'not horrible,' it was noted to be slightly less precise initially and showed more movement at distance, potentially due to trigger differences. Both firearms were tested in a snowy outdoor environment.

This review delves into the Charter Arms 'Dual Pathfinder' or 'Pathfinder Combo' convertible .22 revolver, exploring its history and performance. The reviewer, an experienced firearms instructor, shares findings from extensive research and personal range tests, comparing .22LR and .22 Magnum cylinder performance. Key takeaways include historical context from 1970s magazines and catalogs, insights into cylinder interchangeability issues between older and newer models, and the primary design intent of the Dual Pathfinder as a .22LR firearm with an optional .22 Magnum cylinder.

Amber and Doshie from Exile Armory showcase a wide array of new firearms and accessories. The video features various pistols, rifles, shotguns, and suppressors from brands like FN, Q, Bergara, Springfield Armory, and Beretta, with detailed pricing and some technical specifications provided.

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.
