.450 Xtreme Hunter, reloaded

.450 Bushmaster ammunition, loaded with a solid-copper 220-grain penetrator bullet. Born from discontent with the .223 Remington's weak stopping potential, the .450 Bushmaster round was crafted in line with the so-called 'Thumper' concept: an envisioned need for a large-bore, semi-automatic sporting cartridge capable of downing game in one shot. Along with its elder sibling, the .50-caliber Beowulf cartridge, the .450 Bushmaster is one of a number of such high-caliber rounds and is compatible with appropriately converted AR-15-platform rifles. This particular cartridge is loaded with a solid-copper projectile: excellent at punching through thick barriers and delivering massive amounts of energy to anything unfortunate enough to be hit.
