Duration: 13:20

This video provides a comprehensive comparison of 9mm +P, .30 Carbine, and .357 Magnum through rigorous barrier testing, including steel, concrete, and wood. It details velocity, energy, and terminal ballistics in gel, highlighting significant differences in penetration and energy transfer between the calibers. The testing reveals that while .357 Magnum and .30 Carbine excel in steel penetration, .30 Carbine shows superior accuracy in wood, and all calibers demonstrate varying effectiveness against concrete.

Quick Summary

In barrier testing, .30 Carbine and .357 Magnum penetrated 1/8" steel, while 9mm +P only dented it. Against 3/16" steel, .30 Carbine penetrated cleanly, but .357 Magnum did not. All calibers failed to penetrate concrete. In ballistic gel, .30 Carbine penetrated 20.25" and .357 Magnum exceeded two blocks.

Frequently Asked Questions

How did 9mm +P, .30 Carbine, and .357 Magnum perform against 1/8" steel?

In the 1/8" mild steel test, both .30 Carbine and .357 Magnum successfully penetrated the plate, leaving clean holes. The 9mm +P round, however, failed to penetrate and only managed to leave a significant dent on the steel surface.

Which caliber penetrated 3/16" steel the best?

The .30 Carbine demonstrated superior performance against 3/16" mild steel, achieving a clean penetration. In contrast, the .357 Magnum round, while powerful, was unable to penetrate this thicker steel plate, resulting in a substantial dent.

What were the muzzle energy results for the tested calibers?

From their respective carbine barrel lengths, the tested calibers showed significant energy differences. The 9mm +P registered 617 ft/lbs, the .30 Carbine produced 949 ft/lbs, and the .357 Magnum delivered the highest energy at 1,108 ft/lbs.

How did the calibers perform in ballistic gel testing?

In ballistic gel, the 9mm +P penetrated 16.25 inches. The .30 Carbine achieved a penetration depth of 20.25 inches. The .357 Magnum significantly exceeded the first block and barely exited the second, indicating substantial energy transfer.
