Frequently Asked Questions

How does 10mm Auto compare to .40 S&W in ballistics gel tests?

In tests using Underwood Ammo 180gr JHP from a Glock Gen 4 Model 20, the 10mm Auto showed more violent expansion and a slightly wider wound channel (0.912 inches) than the .40 S&W (0.859 inches), with both fully penetrating 16 inches of gel.

What firearm was used for the .40 S&W and 10mm ballistics comparison?

The comparison utilized a single Glock Gen 4 Model 20 pistol chambered in 10mm Auto. This ensured consistency in barrel length and platform for both the .40 S&W and 10mm rounds fired into the ballistics gel.

What metrics are important for comparing bullet performance in ballistics gel?

Key metrics include penetration depth, projectile expansion (visual and measured), weight retention of the recovered projectile, and the width of the resulting wound channel, all measured under consistent conditions.

What type of ammunition was tested by Kentucky Ballistics?

Kentucky Ballistics tested Underwood Ammo 180-grain Jacketed Hollow Point (JHP) rounds for both the .40 S&W and 10mm Auto calibers during their ballistics gel comparison.
