Underwood 334 45ACP+P 230gr JHP Ammo - 20 Round Box

The Underwood Ammo 334 delivers maximum stopping power through precision-engineered 45ACP+P ammunition loaded with 230-grain jacketed hollow points. This premium defensive ammunition combines increased pressure loading with proven bullet design to achieve superior terminal ballistics compared to standard 45ACP rounds.

What Makes This Different

Underwood's +P pressure loading generates approximately 15% more velocity than standard 45ACP ammunition while maintaining SAAMI pressure specifications. The 230-grain jacketed hollow point bullet expands reliably through heavy clothing and intermediate barriers. Each cartridge undergoes quality control testing to ensure consistent powder charges and proper bullet seating depth.

Key Features

• 230-grain jacketed hollow point bullet optimized for controlled expansion
• +P pressure loading for increased muzzle velocity and energy
• Flash-suppressed powder reduces muzzle signature in low-light conditions
• Nickel-plated brass cases resist corrosion and aid extraction
• Compatible with all 45ACP firearms rated for +P pressures
• Boxer-primed cases suitable for reloading
• 20 rounds per box, 10 boxes per case (200 total rounds)

This ammunition performs consistently across temperature ranges from -20°F to 140°F, making it suitable for duty carry, home defense, and competitive shooting applications. The jacketed hollow point design penetrates 12-18 inches in ballistic gelatin while creating a wound channel approximately 0.75 inches in diameter. Law enforcement agencies specify similar loadings for their standard-issue ammunition due to the proven terminal performance.
