The Hornady American Whitetail .450 Bushmaster 245gr InterLock load (Hornady part no. 82242) is a 20-round box of .450 Bushmaster deer season ammunition from Hornady, built around a 245-grain InterLock bullet. In Hornady’s published data from a 20-inch test barrel, it leaves the muzzle at 2200 fps with 2633 ft-lb of energy. The InterLock bullet is Hornady’s exposed-lead-tip design with a secant ogive profile and an InterLock ring, a raised ring inside the jacket that locks the jacket to the core during expansion. It is a practical pick for confirming your zero ahead of the season and then hunting with the same load.
