Underwood Ammo 458 SOCOM 300gr JHP Ammunition - 20 Rounds

The Underwood Ammo 458 SOCOM 300 grain jacketed hollow point delivers devastating terminal performance for big game hunting and tactical applications. This premium ammunition transforms the AR-15 platform into a hard-hitting powerhouse capable of taking down the largest North American game.

What Makes This Different

Underwood's 458 SOCOM load pushes a 300-grain JHP bullet at velocities exceeding 1,900 fps, generating over 2,400 foot-pounds of muzzle energy. The jacketed hollow point design ensures controlled expansion while maintaining deep penetration through heavy bone and tissue. Standard 458 SOCOM factory loads often underperform compared to Underwood's maximum-pressure loadings that fully utilize the cartridge's potential.

Key Features

• 300-grain jacketed hollow point bullet for maximum terminal performance
• Nickel-plated brass cases resist corrosion and provide smooth feeding
• Flash-suppressed powder reduces muzzle signature in low-light conditions
• Compatible with standard AR-15 lower receivers and 458 SOCOM uppers
• Consistent velocities within 15 fps standard deviation
• Premium small rifle primers ensure reliable ignition
• 20 rounds per box for extended range sessions

This ammunition excels in hunting scenarios where deep penetration through heavy cover is essential. The 300-grain bullet retains energy effectively at extended ranges, making clean kills on elk, bear, and wild boar achievable beyond 200 yards. Law enforcement agencies appreciate the immediate stopping power and barrier penetration capabilities for specialized applications.
