A detachable magazine holding ten cartridges of .450 Bushmaster ammunition is designed for use with firearms chambered for this specific caliber. The .450 Bushmaster cartridge is a large-bore, straight-walled round developed for hunting and certain tactical applications. These magazines typically employ a spring and follower mechanism to feed cartridges into the firearm’s action.
The capacity restriction to ten rounds often reflects legal requirements in certain jurisdictions. The .450 Bushmaster cartridge offers significant stopping power, making it a popular choice for hunting medium to large game at shorter ranges. The development of this cartridge and compatible firearm platforms addressed a demand for a powerful round suitable for use with AR-platform rifles.
