This video provides an expert-level analysis of two high-performance 10mm Underwood Ammunition loads: the Platinum Edition Xtreme Defender and the Nosler JHP. The host, demonstrating significant expertise through rigorous testing, utilizes a Glock 20 and a chronograph to measure muzzle velocity, energy, penetration, and weight retention in ballistic gel after simulating clothing barriers. The Xtreme Defender showcases extreme penetration with 100% weight retention, while the Nosler JHP offers substantial expansion.

Quick Summary

Expert analysis of Underwood 10mm ammunition reveals distinct performance characteristics. The Platinum Edition Xtreme Defender (115gr) offers superior penetration (22.5 inches) and 100% weight retention, ideal for barrier defeat. The Nosler JHP (150gr) provides substantial expansion within 15.25 inches of penetration, suitable for less obstructed targets. Both loads delivered significant muzzle energy, though slightly below advertised velocities.

Frequently Asked Questions

What are the key terminal ballistics differences between Underwood's Platinum Edition Xtreme Defender and Nosler JHP 10mm loads?

The Xtreme Defender (115gr) achieved 22.5 inches of penetration with 100% weight retention, ideal for barrier penetration. The Nosler JHP (150gr) penetrated 15.25 inches with significant expansion but some jacket separation, offering more traditional hollow-point performance.

How did the tested velocities compare to the advertised box ratings for these Underwood 10mm rounds?

Both rounds slightly underperformed their advertised box velocities. The Xtreme Defender tested at 1631 fps (vs. 1700 fps box), and the Nosler JHP tested at 1422 fps (vs. 1500 fps box), though both still delivered substantial muzzle energy.

What firearm was used for the 10mm ammunition testing, and what were its specifications?

The test firearm was a Glock 20 Gen 4, chambered in 10mm Auto, equipped with a 4.6-inch barrel. This platform is well-suited for handling the power of 10mm ammunition.

What methodology was employed to test the terminal ballistics of the 10mm ammunition?

The test involved firing rounds through a simulated heavy clothing barrier into calibrated ballistic gel. A chronograph measured muzzle velocity and energy, while recovered projectiles were weighed and measured for expansion and penetration depth.
