WSM. Ballistics beyond belief.
Release Date: 1/1/2004
Winchester Short Magnum
The introduction of the Winchester Short Magnum family of cartridges in 2000 proved to the world that the word “Magnum” doesn’t always mean bigger. It does, however, mean better, with more speed and hard-hitting downrange energy.
When compared ballistically to their conventional, long action counterparts, the three WSM cartridges produce similar muzzle velocity, down range velocity, energy and trajectory. However, depending on bullet weight and type, the WSM cartridges exceed the ballistics of the conventional 270 Winchester and 7mm Remington Magnum and 300 Winchester Magnum.
With that, why choose a rifle chambered for the WSM cartridges when the ballistics of the conventional, long-action cartridges are so similar? The answers are revealed in the rifles that fire these powerhouse cartridges themselves — the WSM rifles are
Prior to the introduction of the WSM, short-action cartridges capable of delivering high muzzle velocities did so with lightweight bullets and low-level downrange energy.
To enter the realm of high velocity and high energy, beefed-up, belted magnum cartridges and heavyweight rifles were required. The WSM family of calibers has changed all that. By introducing long-action, belted magnum ballistics to the world of lightweight, short-action rifles, WSM calibers have effectively re-written the rules that govern what a hard-hitting, high velocity rifle can be. Rifles chambered in WSM calibers, unlike their long action counterparts, are lighter, faster handling and more accurate
thanks to the shorter, stiffer action.
