10mm vs 357 magnum performance test with ballistics gel

Published on November 4, 2020
Duration: 9:47

This video compares the ballistic performance of 10mm Auto and .357 Magnum using Hornady XTP ammunition fired into ballistic gel. The 10mm, with a 200-grain XTP from a 4.5-inch barrel, averaged 1244 fps and 687 ft-lbs of energy. The .357 Magnum, with a 158-grain XTP from a 3-inch barrel, averaged 1176 fps and 485 ft-lbs of energy. In gel tests, the 10mm showed greater expansion and a wound track of approximately 17 inches, while the .357 Magnum exhibited milder expansion but achieved deeper penetration around 23.5 inches, highlighting its advantage in sectional density for penetration-focused applications.

Quick Summary

In a ballistic gel test, the 10mm Auto (200gr XTP) averaged 1244 fps and 687 ft-lbs, showing greater expansion but 17 inches of penetration. The .357 Magnum (158gr XTP) averaged 1176 fps and 485 ft-lbs, with milder expansion but achieving deeper penetration around 23.5 inches due to higher sectional density.

Frequently Asked Questions

What were the average velocities and energies for the 10mm and .357 Magnum in the test?

The 10mm Auto (200gr XTP) averaged 1244 fps and 687 ft-lbs of energy. The .357 Magnum (158gr XTP) averaged 1176 fps and 485 ft-lbs of energy. These figures were derived from chronograph readings over five shots for each caliber.

How did the 10mm and .357 Magnum perform in ballistic gel regarding penetration?

The 10mm Auto's 200-grain XTP achieved approximately 17 inches of penetration in the ballistic gel. The .357 Magnum's 158-grain XTP, however, penetrated deeper, reaching around 23.5 inches, indicating superior performance in this aspect.

Which caliber showed more bullet expansion in the ballistic gel test?

The 10mm Auto's 200-grain Hornady XTP demonstrated more significant expansion in the ballistic gel compared to the .357 Magnum's 158-grain XTP. The 10mm's expansion was described as quick and substantial.

Does barrel length significantly affect the comparison between 10mm and .357 Magnum?

The presenter argues that for this comparison, the barrel lengths were effectively similar. A 4.5-inch semi-auto barrel includes the chamber, and a 3-inch revolver barrel does not, making the effective projectile travel distance comparable and the comparison fair.
