Underwood Xtreme Penetrator 380 ACP
Underwood Ammunition's Xtreme Penetrator line represents a thoughtful approach to defensive and hunting ammunition for the .380 ACP cartridge.
Key Specifications
- Caliber: .380 ACP (9mm Browning Short)
- Bullet Weight: 90 grains
- Bullet Construction: Copper solid (monolithic)
- Packaging: 20 rounds per box
Design Philosophy
The copper solid bullet design eliminates the traditional lead core, creating a single-piece projectile engineered for consistent, deep penetration. This construction method reduces fouling in the bore and provides reliable expansion characteristics across varying velocities.
The 90-grain weight represents a balanced choice for the .380 ACP platform—substantial enough to deliver meaningful energy while remaining compatible with the cartridge's modest power envelope.
Performance Characteristics
Copper solid ammunition typically delivers:
- Consistent penetration through intermediate barriers
- Reduced barrel fouling compared to traditional ammunition
- Reliable feeding in most .380 ACP firearms
- Predictable ballistics shot to shot
Whether you're seeking reliable practice ammunition or a duty round for your compact .380, Underwood's Xtreme Penetrator offers a proven design backed by a manufacturer known for quality control and performance consistency.
