10mm: The Powerful Pistol Cartridge
The 10mm Auto, also known as the 10mm Norma, is a powerful semi-automatic pistol cartridge that was introduced in 1983. It was designed by Jeff Cooper, a well-known firearms expert, and was intended to be a more powerful alternative to the .45 ACP.
Origins and Design
The 10mm was designed to be a more powerful version of the .45 ACP, with a slightly longer case and a larger caliber bullet. The cartridge case is 25.2mm long, which is slightly longer than the .45 ACP case. The bullet diameter is 10.2mm, which is larger than the .45 ACP's 11.5mm.
Performance
The 10mm has a reputation for being a powerful cartridge, with a muzzle energy of around 750-850 ft-lbs. This makes it suitable for hunting larger game, such as deer and wild boar. The cartridge is also known for its flat trajectory, making it suitable for precision shooting at longer ranges.
History
The 10mm was first introduced in 1983, with the introduction of the Bren Ten pistol, designed by Jeff Cooper. The cartridge gained popularity in the 1980s, with several firearms manufacturers offering pistols chambered in 10mm.
Popularity and Uses
The 10mm has a dedicated following among handgun enthusiasts, particularly those who appreciate its power and range. The cartridge is popular among hunters, competitive shooters, and law enforcement officers. It is also used for self-defense, as its power and penetration make it effective against larger targets.
Weaknesses and Controversies
One of the main criticisms of the 10mm is its high recoil, which can be difficult for some shooters to manage. Additionally, the cartridge's high power can make it difficult to control, particularly for smaller shooters.
In the 1990s, the FBI adopted the 10mm as their standard-issue sidearm, but later switched to the .40 S&W due to concerns about the 10mm's high recoil.
Conclusion
The 10mm is a powerful and versatile cartridge that is well-suited for a variety of applications, from hunting to self-defense. While it may have its weaknesses, the 10mm remains a popular choice among handgun enthusiasts and professionals alike.
