Underwood Range Supply 10mm Auto Ammo 180 Grain Full Metal Jacket - 297

Underwood Range Supply 10mm Auto 180 grain FMJ ammo is designed to deliver consistent performance for training and range use. This load features a full metal jacket projectile that supports reliable feeding and smooth cycling in a wide range of 10mm Auto pistols. With a muzzle velocity of 1,250 feet per second and 625 foot-pounds of energy, it provides a full-power 10mm profile with stable, repeatable performance. The non-expanding bullet maintains its structure on impact, making it well suited for target shooting and practice. Loaded in boxer-primed brass casings, it offers dependable ignition and reloadability. Available in 50-round boxes or 500-round cases, with bulk ammo shipping free through Target Sports USA.

Features and Specifications:

  • Caliber: 10mm Auto ammo for semi-automatic handgun platforms
  • Bullet Type: 180 grain Full Metal Jacket (FMJ) for reliable feeding and consistent function
  • Velocity: Muzzle velocity of 1,250 fps for full-power performance
  • Flash Suppressed Powder: Helps reduce visible muzzle flash in low-light conditions
  • Packaging: 50-round boxes or 500-round cases

Deep Dive

Overview

Underwood Range Supply 10mm Auto 180 grain FMJ ammunition is built to provide reliable, consistent performance for training, target shooting, and routine range use.

The 1,250 fps velocity offers a true-to-caliber shooting experience with stable recoil characteristics, making it suitable for practice, drills, and maintaining familiarity with full-power 10mm performance. This load is commonly used by shooters who want dependable function and repeatable results in their 10mm platforms.

This is what a true 10mm load feels like. Performed well and fed reliably in my M&P 10mm.
