The 243 WSSM was well ahead of its time when it was released. It's even possible that it's been utilized on nearly every continent. It's a rifle cartridge that was first released in 2003. It is a high-velocity round based on ballistics design concepts that are designed to provide a high degree of efficiency, and it employs a.300 WSM case that has been shortened and necked down to take a.243in/6mm diameter bullet. It has been used as a hunting caliber in North America, Europe, Africa, and other parts of the world. Prior to the introduction of more current calibers, it was also proved as a competitive caliber in long-range precision shooting.
Two deer, antelope, and black bear loads are available for the.243 WSSM. One employs moly coated 95-grain Ballistic Silvertip bullet (BC.379, SD.230) with a muzzle velocity of 3250 fps and muzzle energy of 2258 ft. lbs. The second load is designed for hunting medium-sized games. It has a muzzle velocity of 3110 feet per second and muzzle energy of 2147 foot-pounds. It shoots a Power Point bullet with a weight of 100 grains (SD.242).
The case of the 243 WSSM is particularly short and fat in profile, in comparison to most other rifle cartridges. With a 55-grain (3.6 g) projectile, it has a muzzle velocity of 4,060 ft/s (1,240 m/s). As a result, this cartridge is commonly employed for small game like varminting as well as larger species like deer.
The feed and function are two key drawbacks of the.243 WSSM. It is extremely difficult to feed, and in the majority of cases, it fails. Because of the case's extremely steep shoulders from the neck to the large magnum body, it had a difficult time feeding in a bolt action platform.
