What is cal.25?

Caliber .25 (also known as .25 ACP or 6.35mm) is a small, low-power cartridge designed for use in semi-automatic pistols. It was invented in Belgium in 1905 by John Browning and quickly gained popularity due to its small size and lightweight.

The cartridge uses a small, rimless case that typically holds 6-8 rounds of ammunition. The bullet weighs between 40-50 grains and travels at a velocity of around 800 feet per second.

While the caliber .25 is not particularly powerful, it is popular among those who prefer a small and easy-to-carry concealed firearm. It is often used for self-defense, as well as for recreational shooting and plinking.

Some common pistols chambered for the .25 caliber include the Beretta Model 21, Colt 1908, and the FN Baby Browning. Despite its popularity, however, the caliber has been largely overshadowed in recent years by more powerful rounds such as the 9mm and .40 S&W.
