Alexander Arms .50 Beowulf 300-grain Hornady FTX ammunition (brand part no. AB300FTXBX) combines the big-bore stopping power the cartridge was built for with a bullet engineered for controlled, reliable expansion. Alexander Arms, the company that developed the .50 Beowulf cartridge, loads it here with Hornady’s FTX, a polymer-tipped bullet whose soft nose compresses into the bullet on impact to trigger immediate expansion across a wide range of velocities. An InterLock ring mechanically locks the lead core to the jacket, so the bullet retains weight and drives deep even through heavy bone. Built for AR-platform rifles chambered in .50 Beowulf, this load is sized for hunters and defenders who want maximum energy transfer on large or heavy-bodied game.
