Description:

This cartridge was introduced in the United States along with the Browning-designed, Colt manufactured 'Vest Pocket' pistol. Also referred to as the 6.35mm Browning, this semi-rimmed centerfire cartridge has fairly high velocity for such a small size. However, the energy it delivers at any range is quite low. This, combined with the full metal jacketed bullet, adds up to a very poor stopping or killing power on anything. The .25 ACP is not powerful enough for hunting anything but pests, nor is it adequate for serious self defense. However, the .25 auto caliber pistols are popular because of their small size and low cost.
