Federal American Eagle 450 Bushmaster 260-grain Full Metal Jacket ammunition (brand part no. AE450BM) gives big-bore AR-platform shooters an affordable way to run rounds through a straight-wall cartridge built for serious knockdown power. Federal Ammunition loads the American Eagle line specifically for range practice, so shooters can sight in, function-test a new upper, or simply burn through rounds without spending hunting-load money. The 260-grain full metal jacket bullet feeds reliably and holds together through the impact energy of the 450 Bushmaster case, mirroring the trajectory shooters will see from expanding hunting ammunition in the same platform. For anyone prepping a 450 Bushmaster rifle before hunting season or just enjoying the cartridge’s raw output at the range, this is the practice load to burn through first.
