The Underwood Ammo 242 10mm Auto 220gr Hard Cast Flat Nose is engineered as high performance handgun ammunition for demanding woods and hunting use. Each round pairs a heavy 220 grain flat nose hard cast bullet with nickel-plated brass casing, delivering reliable feeding and deep, straight-line penetration on tough game.

This load uses Underwood’s Black Cherry polymer coating on the hard cast lead projectile to virtually eliminate lead fouling, reduce friction, and withstand high heat and pressure. Flash-suppressed powder helps preserve your sight picture in low light, while supersonic muzzle velocity and substantial energy make it suitable for medium to large and dangerous game where dependable penetration is critical. Backed by Underwood’s reputation for consistent, carefully assembled ammunition, this 10mm Auto round is built for shooters who need confidence in every shot.
