This YouTube video features an "autopsy" of an AR-15 upper receiver that experienced a rare malfunction: a broken buffer spring. The video investigates a Green Sprinco buffer spring that failed after 2780 rounds, potentially due to corrosion from corrosive South African ammunition. Additionally, the video includes a physical examination of a SOLGW Scalper BCG. The content focuses on a specific firearm component failure and its potential causes, as well as an accessory inspection.
This video provides an in-depth evaluation of 1941 Turkish 8mm Mauser ammunition. The analysis covers the historical context of its adoption by Turkey post-WWI, its resemblance to the German 8mm S cartridge, and its common packaging. A significant portion of the video is dedicated to testing the ammunition's performance and safety. The presenter details velocity measurements using a Kar98k rifle, noting an average velocity of 2948 fps and highlighting symptoms of overpressure such as increased recoil and stock damage. Bullet weight analysis shows consistency, with an average of 154.3 grains. The ammunition is identified as having Berdan primers and corrosive properties, and the cases are brass. The video strongly cautions against using this ammunition in semi-automatic firearms due to its reputation for causing damage from increased pressure.
This video provides a comprehensive evaluation of Ethiopian .30-06 ammunition imported by Century International Arms. The analysis covers the ammunition's appearance and packaging, live-fire testing including velocity and consistency, and a teardown to assess bullet weight consistency. The ammunition is believed to be produced at the Emperor Haile Selassie Ammunition Factory in Addis Ababa, with a headstamp of 1977. It's intended for American surplus rifles and machine guns like the M1 Garand, M1917, M1919, and M1918A2 BAR. The testing revealed higher than expected velocities, with a flat-base, gilding metal over steel jacketed bullet construction that attracts a magnet. The video notes the ammunition is advertised as corrosive.
