Underwood 450 Bushmaster 220gr - Xtreme Hunter 20rd 10bx/cs

The Underwood 450 Bushmaster 220gr Xtreme Hunter ammunition delivers devastating stopping power for hunters and tactical shooters who demand performance beyond conventional rifle rounds. Designed for the .450 Bushmaster platform—a purpose-built cartridge engineered for maximum terminal effect at intermediate ranges—this 20-round box represents a premium hunting and self-defense solution. Whether deployed in AR-platform rifles or bolt-action builds, the Xtreme Hunter line addresses the need for controlled yet lethal energy transfer in medium to large game applications and tactical engagements.

This 220-grain load achieves a muzzle velocity of 2,385 feet per second, balancing recoil management with deep penetration and consistent expansion at typical hunting distances. The projectile weight and velocity combination generates sufficient kinetic energy for reliable energy transfer while maintaining controllability for follow-up shots—a critical factor in both hunting and defense scenarios. Underwood's manufacturing standards ensure consistent powder charges, primer ignition, and bullet construction across all 20 rounds in each box, minimizing shot-to-shot velocity variation and supporting accuracy at distance. The cartridge design accommodates the larger bore diameter of the .450 Bushmaster platform, maximizing the ballistic efficiency of this intermediate-range hunting round.

This ammunition is purpose-built for .450 Bushmaster-chambered rifles, including AR-15 upper assemblies and dedicated platform rifles designed around this cartridge. Hunters pursuing medium to large game—whitetail, feral hog, and similar species—benefit from the round's terminal performance and intermediate-range capability. Tactical shooters and sport shooters working within the effective range envelope of the .450 Bushmaster will find the consistent performance and quality control of Underwood Ammo suitable for both training and duty applications. Each case includes 10 boxes of 20 rounds, providing a practical quantity for inventory, practice, and field use. Proper storage in a cool, dry environment preserves the ammunition's reliability and performance integrity.
