History of ACP
The Automatic Colt Pistol cartridge was born out of the need for a reliable and efficient pistol cartridge. In the early 1900s, Colt’s Patent Firearms Manufacturing Company was looking to develop a cartridge that could fire multiple shots without manual re-cocking.

It was designed to be powerful, reliable, and efficient, making it an excellent choice for military and civilian use. Over the years, the ACP designation has been used for a range of cartridges, from the.22 ACP to the.40 S&W.

ACP cartridges are designed to be used in semi-automatic pistols and are known for their reliability and consistency. Here are some key characteristics of ACP cartridges:
- Copper Jacket: ACP cartridges feature a copper jacket surrounding the lead core, which helps to reduce fouling and improve accuracy.
- Full Metal Jacket (FMJ): The copper jacket is designed to be full metal jacket, which means it’s crimped onto the case to prevent the bullet from coming loose during firing.
- Case Dimensions: ACP cartridges have standardized case dimensions, which ensure compatibility with a wide range of firearms.
- Powder Charge: The powder charge in ACP cartridges is designed to produce a consistent and reliable expansion of the bullet.
