45ACP VS 10MM Auto: Which is King?

Published on July 24, 2024
Duration: 11:04

This video compares the 10mm Auto and .45 ACP handgun calibers, arguing that 10mm is superior in most scenarios due to its higher velocity and energy. The presenter emphasizes that modern bullet technology has leveled the playing field for many calibers, but 10mm offers a distinct advantage for defense against larger game. The video also highlights the importance of training, regardless of caliber choice.

Quick Summary

The 10mm Auto is generally considered superior to the .45 ACP due to its higher velocity and energy, offering better penetration for defense against larger game. While modern bullet technology has improved .45 ACP performance, 10mm's ballistics provide a distinct advantage in power and effectiveness.

Frequently Asked Questions

What are the key differences in ballistics between 10mm Auto and .45 ACP?

10mm Auto generally pushes heavier bullets at significantly higher velocities than .45 ACP. Typical .45 ACP defensive rounds are subsonic (890-950 ft/s) with around 400 ft-lbs of energy, while 10mm can achieve over 1200 ft/s with comparable or heavier bullets, delivering substantially more energy, making it more effective for deep penetration.

When would .45 ACP be a better choice than 10mm Auto?

According to the presenter, the only scenarios where .45 ACP might make sense over 10mm are for collectible submachine guns or if one strictly shoots suppressed. However, even in suppressed applications, 9mm might be considered superior to .45 ACP.

How does modern bullet technology affect the comparison between 10mm and .45 ACP?

Modern bullet technology, featuring advanced designs for penetration and expansion, has largely leveled the playing field between many pistol calibers. While this makes calibers like 9mm very capable, 10mm still retains an edge for specific applications requiring superior penetration and energy, especially against larger game.

What is the presenter's overall opinion on .45 ACP versus 10mm Auto?

The presenter strongly favors 10mm Auto, considering it superior to .45 ACP in almost all scenarios. They describe .45 ACP as a 'lethargic, fat, and slow' round, while praising 10mm for its superior ballistics and effectiveness, particularly for defense against larger threats.
