Cartridge History: The .451 Detonics Magnum is a Supercharged .45 ACP
This video delves into the history of the .451 Detonics Magnum cartridge, a powerful variant of the .45 ACP developed by Detonics. Founded in the 1970s and known for their high-end 1911 pistols, Detonics sought to create a higher-power .45 round that would fit within a standard 1911 magazine. They achieved this by modifying .45 Winchester Magnum brass, increasing pressure, and boosting velocity by 30% over the .45 ACP. While Detonics produced various pistols chambered in .451, the lack of commercial ammunition manufacturing limited its widespread adoption, leaving it a niche cartridge. Its lineage is traced to later developments like the .45 Super and .460 Rowland.
