 Ballistically, the .450 Bushmaster has a rather flat trajectory out to 200 yards; if the firearm is zeroed at 150 yards, the user can expect to see a rise of 1.8 inches at 100 yards, zero at 150 yards, and a drop of 4.9 inches at 200 yards.The cartridge fits single-stacked in a standard AR-15 magazine with a single-stack follower.A 10-round AR-15 magazine body yields a four-round  magazine, a 20-round AR-15 magazine body yields a five to seven-round  magazine, and a 30-round body yields a nine-round  magazine.
