Gun Descriptions

.45 Auto (.45 ACP)

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.

450 SMC

About The .450 SMC Ammo was launched in the late 2000s and was similar to the .45 Super. The main difference was that this cartridge used a small rifle primer which allowed more brass into the cartridge to provide it with more strength. Despite getting discontinued and fading away, the .450 SMC Ammo is now commercially available in the markets. The .450 SMC Ammo uses a small magnum primer rather than the primer of a standard pistol cartridge which provides plenty of ignition power. Small primer means more brass at the base of the bullet, meaning more strength to the case. The recoil in the lighter variants of the .450 SMC Ammo is pretty similar to the .45 ACP Ammo, but when it comes to heavier rounds, the .450 SMC Ammo provides far more controllable and manageable recoils. People have been praising the manufacturers who brought back the .450 SMC Ammo into the markets because of its performance and reliability to shooters for different purposes. Manufacturer The .450 SMC Ammo was originally produced by Triton in the late 2000s but was discontinued. Mike McNett, the founder of Doubletap Ammunition, saw potential in this cartridge and decided to bring it back and better than before. Uses The lighter rounds are being used widely for self-defense because they can be shot fast and accurately. The heavier rounds can take down medium-sized game and a few large species in decent range.
