About
The .25 ACP Ammo is a semi rimmed, straight walled centerfire cartridge for pistols that was introduced into the markets in 1905. The bullet was designed using the semi-rimmed cartridge structure, meaning the rim of the casing protrudes a little beyond the diameter of the base of the bullet casing so that it can add headspace to the rim. Even though the .25 ACP Ammo was mainly created to be chambered into pistols, many revolvers were introduced in the early twentieth century that could be used with this ammo. The .25 ACP Ammo works mainly with compact, lightweight pistols and delivers low-powered shots in short range. The overall length of the .25 ACP Ammo is 23mm, while the bullet's diameter measures 6.4mm. The 50-grain bullet is the heaviest variant of the .25 ACP Ammo that can travel at a velocity of 760 feet per second, creating an energy level of 65 ft.lbf.Â
Manufacturer
The .25 ACP Ammo was created in United States & Belgium in 1905 by John Browning.Â
Uses
The .25 ACP Ammo is used with small and light pistols that deliver a less powerful shot in a short range. But because of its centerfire case design, the shots taken with the .25 ACP Ammo are more reliable, making it a good choice for self-defense.Â
45 ACP
45 ACP (Automatic Colt Pistol) Ammo is a popular handgun cartridge that is perfect to use in legendary 1911 pistols. These hard-hitting rounds are well-known around the world for both stopping power and reliability. The muzzle energy of 45 ACP ammo ranges between 300 and 500 ft. which is higher than most 9mm cartridges. Introduced in 1904 by John Moses Browning, this rimless straight-walled handgun standard cartridge operates at a low chamber pressure rating of 21,000 psi.
