The 10mm Auto is a high-performance cartridge known for its powerful impact and versatility. Introduced in 1983, it has become a popular choice for self-defense, law enforcement, and in some cases even hunting. The 10mm bullet, with a diameter of 10.16mm and a case length of 25.2mm, offers superior stopping power compared to the 9mm Luger, firing bullets typically between 155 and 200 grains.
Characteristics of the 10mm Auto include its high muzzle velocity, which ranges from 1,200 to 1,400 feet per second, delivering significant energy and recoil. This makes 10mm ammo effective for both personal defense and taking down larger game. However, its powerful recoil can be a disadvantage for some shooters, and its higher maintenance requirements and ammunition cost are notable drawbacks.
The 10mm Auto cartridge is a very powerful handgun caliber, primarily used in 1911 handguns, but also in some Glock pistols and SIG Sauer models.
What is 10mm Auto?
The 10mm Auto is a semi-automatic pistol cartridge known for its high power and versatility. It was developed in 1983 by Jeff Cooper and introduced with the Bren Ten pistol. The cartridge features a bullet diameter of 10.16mm (0.40 inches) and a case length of 25.2mm (0.99 inches). It typically fires bullets weighing between 155 and 200 grains, with muzzle velocities ranging from 1,200 to 1,400 feet per second.
The 10mm Auto is valued for its stopping power and effectiveness in various roles, including self-defense, law enforcement, and hunting small game.

How can 10mm ACP Damage the Human Body?
The 10mm Auto can cause severe damage to the human body due to its high kinetic energy and bullet velocity. When a 10mm Auto round impacts, it delivers significant force that can penetrate deep into tissue and organs. The cartridge’s muzzle energy, typically between 500 to 700 foot-pounds, allows it to inflict extensive tissue damage and cause severe trauma.
The large diameter of the 10mm Auto bullet, combined with its high velocity (1,200 to 1,400 feet per second), increases the likelihood of creating large wound channels and extensive cavitation. This can lead to significant internal damage, disrupt vital organs, and cause massive hemorrhaging. The recoil and energy transfer of the 10mm Auto make it more effective at incapacitating a target compared to lower-caliber rounds.
Is 10mm Auto more powerful than .45 ACP?
Yes. The 10mm Auto is generally more powerful than the .45 ACP. The 10mm Auto delivers higher muzzle energy, typically between 500 to 700 foot-pounds, compared to the .45 ACP’s 350 to 450 foot-pounds. Additionally, the 10mm Auto has a higher muzzle velocity, ranging from 1,200 to 1,400 feet per second, whereas the .45 ACP typically ranges from 830 to 950 feet per second. This results in the 10mm Auto having greater overall ballistic performance and stopping power in the 10mm vs .45 ACP debate.
