What is .223 super short mag?

The .223 Super Short Mag (also known as the .223 WSSM) is a rifle cartridge developed by Winchester Repeating Arms in collaboration with Browning Arms Company. It was introduced in 2003 as an extension of the Winchester Super Short Magnum line of cartridges.

The .223 WSSM is based on a shortened and necked-down version of the Winchester .300 WSM case, using a small rifle primer. It has a bullet diameter of .224 inches and a maximum overall length of 2.350 inches.

The cartridge is designed for use in short-action rifles, which allows for a more compact and lightweight firearm overall. It is primarily used for varmint hunting and target shooting, as well as some medium game hunting.

Compared to the standard .223 Remington cartridge, the .223 WSSM offers higher muzzle velocity and increased energy, making it a more powerful and versatile round. However, it also generates more recoil and has a shorter barrel life due to the increased chamber pressure.

Overall, the .223 Super Short Mag is a modern and potent cartridge that offers impressive performance for shooters who demand high velocity and accuracy.
