Hornady's DGX (Dangerous Game Expanding) has a copper-clad steel jacket and high antimony lead alloy core for deep penetration. The flat nose aids in expansion and straight penetration, reducing possible deflections. The serrated nose section of the jacket and the sidewall thickness profile give the ultimate combination of controlled expansion, weight retention and depth of penetration. The heavy, copper-clad steel jacket is 0.098" thick and penetrates deeply through hide, muscle and bone with a patented InterLock ring to lock the core and jacket together, improving retained weight of the expanded bullet.
