Videos tagged with Rimmed Cartridges

This video from C&Rsenal, featuring expert Othais, provides an in-depth comparison of rimmed versus rimless cartridge designs, focusing on the 6.5mm Greek Mannlicher-Schönauer and 6.5mm Dutch. Othais, demonstrating high authority and deep technical knowledge, explains the historical advantages of rimmed cartridges, such as their function as a gas check and ease of extraction, particularly in revolvers. The video details why rimless cartridges became the standard for autoloading firearms due to improved magazine feeding and reliability, avoiding issues like rim lock.

This video provides an expert-level explanation of firearm headspace, detailing four primary methods: rimmed, rimless, case mouth, and belted. Instructor Mark Novak uses a variety of firearms, including a Martini Henry, M1 Garand, FN 49, and 1911s, to illustrate how different cartridge designs headspace and lock up. The explanation covers the critical 'abutment' or 'buck stop' in each system and the importance of precise manufacturing tolerances to ensure safe and reliable firearm operation.

This Q&A session covers a range of firearm topics, including the development of CMMG's Banshee with its radial delayed blowback system for .45 ACP, Calico's helical magazines for rimmed cartridges, and comparisons between the M1 Carbine and SKS. Expert Ian McCollum also discusses the economics of firearm reproductions, the legal status of stocked pistols, and historical firearm cases like the Maroszek Wz. 38M.

This video clarifies the distinction between firearm clips and magazines, showcasing historical and modern examples of both. It details how various systems, from Mannlicher and Mauser rifles to the M1 Garand and modern AR/AK platforms, utilize different types of clips and loading devices for efficient ammunition feeding and reloading.

This Q&A session from Forgotten Weapons covers a range of firearms topics, including the mechanics of gain twist rifling and its applications, comparisons of various rifle cartridges, historical firearm decisions like the US adoption of the M1903 Springfield over the M1917 Enfield, and the design philosophy behind the AR-15. It also delves into the surplus market, collectible firearm acquisition, and the rationale behind certain firearm designs and their perceived reputations.

This guide emphasizes the critical importance of understanding and respecting firearm pressures and headspace during handloading. It warns against dangerous practices like pushing loads to the point of blown primers or difficult bolt lifts, highlighting the potential for firearm damage. The instructor stresses adhering to published load data, starting with reduced charges, and using incremental testing for safe load development. Proper headspace management and the avoidance of corrosive ammunition are also detailed as crucial safety measures for preventing catastrophic failures and preserving firearm integrity.
