• Multiple relief grooves machined into the shank act as pressure relief valves, reducing fouling and allowing safe loading to higher velocities compared to conventional solid shank bullets.
• All-copper construction provides near 100 percent weight retention in soft tissue, which supports deep penetration on heavy bodied game.
• Flat base configuration supports consistent ignition and excellent accuracy in typical 450 Bushmaster barrel lengths and twist rates.
• Lead-free composition makes this bullet suitable for areas or applications where lead projectiles are restricted.
• Purpose built geometry for 450 Bushmaster ensures correct seating depth, cartridge overall length compatibility, and reliable feeding in common magazines.

• The combination of high sectional density and controlled expansion makes this bullet well suited for deer, hogs, and larger game where you want both expansion and through-penetration.
• Relief grooves and the all-copper build help you maintain accuracy over long practice and hunting sessions with reduced barrel fouling and stable velocities.
• The 20 count box size matches how many hunters build a focused batch of hunting loads rather than large volume bulk ammunition.
• If you run a 450 Bushmaster rifle for serious hunting work, the Barnes TSX 45 cal .451 275 grain flat base bullet (30628) is a dependable option for building deep penetrating, lead-free hunting ammunition.
