Underwood 458 Hammmer 302gr - Jhp 20rd 10bx/cs

The Underwood 458 Hammer 302gr JHP 20rd ammunition represents purpose-built power for hunters and tactical shooters demanding deep penetration and controlled expansion in medium to large game. Built on the modern .458 HAM'R platform, this cartridge delivers rifle-class ballistics from compact AR-platform rifles, making it ideal for those who prioritize stopping power without the recoil penalties of magnum rifle cartridges. Each box contains 20 rounds staged for reliable feeding and consistent performance across a wide range of 458-compatible platforms.

Each round fires a 302-grain jacketed hollow-point projectile at a muzzle velocity of 2,100 feet per second, generating substantial kinetic energy and terminal performance. The jacketed hollow-point design initiates controlled expansion on impact while the heavy projectile weight ensures deep penetration through heavy bone and hide—critical factors in ethical hunting and defensive applications. Underwood's quality control and propellant selection ensure velocity consistency, shot-to-shot reliability, and minimal pressure deviation that shooters depend on for hunting accuracy and tactical repeatability.

This ammunition performs optimally in AR-platform rifles and other 458 HAM'R-chambered firearms, delivering its design velocity and expansion characteristics across mid-range to extended distances typical of hunting applications. Law enforcement and military personnel exploring alternative cartridges for specialized operations find the 458 Hammer's combination of power and platform flexibility valuable for precision work. The 20-round box format supports both single-range sessions and field hunting where shot count remains manageable; the case of ten boxes (200 rounds total) provides efficient bulk purchasing for serious shooters and training programs.
