375 Socom

New drawing Coming

The .375 SOCOM is a rifle cartridge specifically designed for the AR-15 platform. Developed by Tromix, it features a .375-inch caliber bullet that provides significant stopping power and is suitable for a variety of uses, including hunting medium to large game, as well as tactical applications. The cartridge was designed to maximize the performance of the AR-15 platform while maintaining compatibility with standard AR-15 magazines.
Balancing substantial kinetic energy and manageable recoil, the .375 SOCOM offers improved terminal ballistics and penetration compared to more traditional AR-15 cartridges like the .223 Remington/5.56 NATO. It's effective at both short and longer ranges, making it versatile for different types of shooting scenarios. Reloading options for the .375 SOCOM are widely available, allowing enthusiasts to customize loads for specific applications.
The .375 SOCOM is particularly popular among hunters who require a powerful cartridge capable of taking down larger North American game such as deer, wild boar, and black bear. Additionally, its stopping power makes it a solid choice for defensive situations.
