Underwood 10mm 200gr Hard Cast Flat Nose Ammunition
Underwood's 10mm hard cast ammunition features 200-grain flat nose projectiles with advanced Black Cherry polymer coating for reduced fouling and enhanced barrel protection.
Premium 10mm Hard Cast Ammunition
Underwood's 10mm ammunition represents a thoughtful approach to handgun ballistics, particularly for shooters who demand reliable performance and minimal maintenance.
The Black Cherry Coating Advantage
The standout feature here is Underwood's proprietary Black Cherry polymer coating—a significant upgrade over traditional hard cast designs. This coating system delivers:
- Superior thermal stability that withstands high-pressure and high-heat conditions
- Reduced lead fouling by preventing direct lead-to-bore contact
- Exceptional wear resistance against gas cutting and abrasion
- Self-lubricating properties that decrease friction in the bore
- Chemical and weather resistance for long-term storage reliability
Performance Specifications
Each 200-grain flat nose projectile launches at 1,250 feet per second, delivering the stopping power and penetration that serious 10mm shooters expect. The flat nose profile enhances accuracy and terminal performance compared to round nose designs.
Compatibility
These rounds function reliably in all 10mm firearms, including modern pistols with polygonal rifling such as Glock models. The coating eliminates the lead fouling concerns that sometimes plague hard cast ammunition in tightly-toleranced barrels.
Practical Benefits
You'll notice the absence of plastic-burning odor at the range—a welcome improvement over older coating technologies. The ammunition's robust construction means you can push velocities higher without sacrificing bore cleanliness or reliability.
Packaged: 20 rounds per box, 10 boxes per case
