The 458 Socom is a bore round initially designed for the AR 15. The idea behind the round was to provide the military with a powerful, fighting stopping round designed for use in close quarters combat. The idea came to be due to troops clearing caves in Afghanistan and their standard 5.56 rounds failing to quickly stop opposing forces. The big bore 458 Socom round nearly replicates the performance of the 45-70 Government, but is better suited for semi-auto actions.
The round was never adopted for military use, but found a home on the civilian market. 458 Socom ammo is naturally subsonic so it's easy to effectively suppress. It also hits some significant force and with the right hollow point load the wound cavity will be massive. This makes a solid hunting round for medium to large game. It's even a capable round for bear.
458 ammo even fits in a standard 30 round AR 15 magazine, but it limits the capacity to ten rounds due to the round’s size.
