Why is .450 Bushmaster popular for hunting?

.450 Bushmaster is a straight-wall rifle cartridge that has become popular among hunters, particularly in areas where hunting regulations restrict or favor straight-wall cartridges. It provides a large-diameter projectile while fitting within an AR-15-style platform, making it an alternative to traditional bottleneck rifle cartridges for certain hunting applications. Hunting regulations vary considerably by state and season, so always verify current caliber, cartridge, firearm, and ammunition requirements where you hunt.
