Underwood 10mm Auto Ammo 135 Grain Jacketed Hollow Point - 231
Underwood 10mm Auto 135 grain Jacketed Hollow Point ammo is designed to deliver high velocity with rapid expansion for defensive use. This load utilizes a Nosler Sporting Handgun bullet featuring a tapered jacket plus lead core, engineered for consistent expansion across a wide velocity range. With a muzzle velocity of 1,600 feet per second plus 768 foot-pounds of energy, it offers a fast, flat-shooting profile with strong initial impact. The lighter 135 grain projectile contributes to increased velocity while helping reduce recoil compared to heavier 10mm loads. Nickel-plated brass casings enhance feeding reliability while resisting corrosion during carry or storage. Available in 20-round boxes or 200-round cases, with bulk ammo shipping free through Target Sports USA.

Deep Dive
Overview
Underwood 10mm Auto 135 grain Jacketed Hollow Point ammunition is built to provide rapid expansion with strong energy transfer in defensive scenarios. The Nosler bullet uses a tapered jacket plus lead core to promote reliable expansion upon impact across varying velocities. Its lighter weight plus higher velocity produce a flatter trajectory while keeping recoil manageable for faster follow-up shots.
