Underwood Ammo's 10mm hard cast ammunition delivers the penetration and reliability serious shooters demand. These 200-grain flat-nose rounds are engineered for hunters and defense-minded pistol shooters who need consistent performance through tough barriers. Each box contains 20 rounds, and the 10-case format gives you a serious supply of ammunition that's ready for the range or the field.
The standout feature here is Underwood's "Black Cherry" polymer coating—a thermal-stability upgrade that handles velocities and pressures other coatings can't match. This coating eliminates lead-to-bore contact, which means virtually no lead fouling buildup in your barrel. You get cleaner shooting sessions, less maintenance, and the ability to push these rounds hard without the residue headaches that plague uncoated lead projectiles. The coating is also self-lubricating, so feeding is smooth and consistent through any 10mm platform, including polygonal rifling common in Glocks.
Built for serious use, the Black Cherry coating resists weathering, chemical degradation, and abrasion—important if you're storing ammo long-term or shooting in variable conditions. It won't produce the plastic-burning smell some coatings do, and the flat-nose profile delivers reliable expansion and energy transfer on game or defensive targets. Whether you're loading for a Glock, 1911, or other 10mm pistol, these rounds function safely across all 10mm firearms.
If you're running a 10mm platform regularly—hunting hogs, competing, or training—Underwood's hard cast ammunition is the kind of dependable, no-nonsense choice that keeps your gun running clean and your hits consistent.
