This video debunks the myth that steel-cased ammunition damages firearms. While modern steel cases are safe for general use, historical issues stemmed from corrosive primers. Steel cases can cause increased extractor wear and carbon blowback due to being less malleable than brass, but the cost savings generally outweigh potential maintenance needs. Certain platforms like the AK-47 are designed for steel, and modern AR-15s also handle it well.
The 7.62x54R cartridge, developed in 1891, remains the world's longest-serving military round. Despite its rimmed design posing feeding challenges, its longevity is due to massive stockpiles and continued use in platforms like the PKM and SVD. The video covers its history, rifle variants from Mosin-Nagant to modern DMRs, ammunition types, and crucial maintenance regarding corrosive primers.
This video is Part 1 of a November 2019 Q&A session, featuring questions from viewers on a variety of firearms-related topics. Discussions cover the role of small arms in a hypothetical Korean War, improvements to the Bianchi UM84 holster, choosing a combat rifle from 1866, the appeal of Red Oktober matches, POI/POA shifts when shooting around barricades, criticisms of specific firearms like the G3, the use of handloads for self-defense, experiencing historical and automatic firearms as a tourist, disconnector functions in open-bolt machine guns, two-gun pistol holsters, aluminum case rifle ammunition, hypothetical 2gACM stage design, cleaning corrosive primers with Ballistol, common firearm misconceptions, personal machine gun collections, footwear choices, preferences for steel targets, leaving a brake on the XCR during trials, Karl's personal firearms history, and the potential use of flux pistol braces for law enforcement and competition.
This evaluation of 1941 Turkish 8mm Mauser ammunition, presented by Ian McCollum of Forgotten Weapons, highlights its dangerous overpressure characteristics. Testing revealed velocities significantly exceeding standard specifications, leading to firearm damage and safety concerns. The ammunition is deemed unsafe for semi-automatic firearms and potentially damaging even to robust bolt-actions due to its 'hot' loading and corrosive nature.
This review of Ethiopian 7.92x57mm Mauser ammunition, produced at the Haile Selassie I Ammunition Factory, reveals performance data from live-fire testing. While exhibiting lower quality than modern ammunition, including hangfires and a corrosive primer, it performed adequately for its intended historical context. The ammunition features spitzer boat-tail bullets and brass cases, with markings indicating a 1947 production date despite 1955 headstamps.
This evaluation of Ethiopian 7.62x51mm NATO surplus ammunition reveals significant age-related degradation, primarily manifesting as frequent hangfires due to primer issues. While bullet weight is consistent at an average of 143.4 grains and velocity averages 2637 fps, the high standard deviation in velocity (33.29 fps) and the presence of hangfires indicate poor storage or component aging. The ammunition, manufactured between 1977 and 1985, is housed in 280-round cans and features a stick-type powder.
