The Underwood Ammo 864 9mm +P 68gr delivers exceptional terminal performance with its solid copper construction and extreme velocity design. This premium defensive ammunition combines lightweight projectile technology with enhanced pressure loading to maximize energy transfer and penetration capabilities.
What Makes This Different
Unlike traditional jacketed hollow points, this solid copper projectile maintains structural integrity while creating devastating wound channels through controlled expansion. The 68-grain weight paired with +P pressure generates velocities exceeding 1,400 fps from standard barrel lengths. This combination produces significantly higher energy levels compared to standard 115-grain or 124-grain defensive loads.
Key Features
- 68-grain solid copper Xtreme Hunter projectile for maximum expansion
- +P pressure loading delivers velocities over 1,400 fps
- Nickel-plated brass cases prevent corrosion and ensure reliable extraction
- Lead-free construction eliminates toxic exposure concerns
- Consistent powder charges maintain shot-to-shot velocity uniformity
- Small primer design compatible with all 9mm firearms
- 20 rounds per box packaging for range testing and carry rotation
Field testing demonstrates reliable expansion across various barrier materials including heavy clothing, wallboard, and automotive glass. The lightweight projectile design reduces felt recoil compared to heavier defensive loads while maintaining superior ballistic performance. Law enforcement agencies and competitive shooters report excellent accuracy and consistent cycling in both full-size and compact pistol platforms.
