The Hornady Back Country Defense Pistol Ammo in 454 Casull with a 300 gr DGH bullet is a purpose-built choice for hunters and guides who carry a backcountry sidearm, and the Back Country Defense series brings a combination of heavy-for-caliber energy and field-focused terminal performance that matters when encounters are close and stakes are high. The Straightline Penetration-Protected point locks the bullet nose to the core to drive maximum straightline penetration while limiting deflection, giving you reliable pass-through performance on thick shoulders and bone; because the jacketed DGH (Dangerous Game Handgun) bullet produces no lead smoke, you see your target and get faster follow-up shots in dense brush or low-light defensive scenarios. With a 300 grain projectile, brass casing, a muzzle velocity around 1820 fps and muzzle energy near 2206 ftlbs, this load delivers the stopping power needed for large game or dangerous-animal defense where deep penetration and retained energy count. If you carry a 454 Casull for mountain hunting, guide work, or remote travel, this Hornady load balances penetration, visible follow-up capability, and raw energy in a compact pistol cartridge.
