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
About
The .45 Auto Rim Ammo, also known as the 11.5x23R, is a rimmed cartridge explicitly designed to be used in revolvers initially chambered for the .45 ACP Ammo. The .45 Auto Rim Ammo was developed in 1920 in the United States. Issues with .45 ACP Ammo led to creating the .45 Auto Rim Ammo. The first issue was that some of the spent cases needed to be removed by hand or a stick, which was a nuisance. The second issue concerned the headspace; the .45 ACP could slip forward in the M1917s, stopping them from being fired. However, adding a rim to the .45 ACP Ammo solved these issues. Loads offered for the .45 Auto Rim ammo were similar to the .45 ACP Ammo but were fully lead bullets. The lead bullets reduced the barrel wear in the shallow revolvers. The overall length of the .45 Auto Rim Ammo is 32.12mm, and the bullet diameter of the cartridge is 11.5mm. The 16-grain bullet is the lightest variant of the .45 Auto Rim Ammo, which can travel at a velocity of 1,050 feet per second and create an energy level of 392 ft.lbf.
Manufacturer
The .45 Auto Rim Ammo was produced by Peters Remington Corbon in 1920.
Uses
The .45 Auto Rim Ammo was created to replace the .45 ACP Ammo in the M1917s because of its gun issues.
