A detachable box magazine designed to hold ten rounds of .450 Bushmaster ammunition provides firepower for this large-bore cartridge, commonly used in AR-platform rifles. These magazines are essential for the practical use of the cartridge in various shooting applications.
The ten-round capacity strikes a balance between ammunition availability for hunting or self-defense and manageable magazine size for comfortable handling and maneuverability. This specific capacity also addresses legal restrictions in some jurisdictions regarding magazine capacity. The .450 Bushmaster cartridge itself offers significant stopping power, making it a popular choice for hunting medium-sized game. Its use in AR-platform rifles allows for a familiar operating system combined with the advantages of a powerful straight-walled cartridge.
