The .243 Winchester Super Short Magnum or .243 WSSM is a rifle cartridge introduced in 2003. It uses a .300 WSM ( Winchester Short Magnum ) case shortened and necked down to accept a .243in/6mm diameter bullet, and is a high velocity round based on ballistics design philosophies that are intended to produce a high level of efficiency.

The .243 produces a velocity of 3,200 feet (980 m) per second from factory-loaded expanding monolithic copper projectiles weighing 85 grains (5.5 g) fired from a 24-inch (610 mm) barrel. [28] Other variations of commercially loaded .243 ammunition are available with bullet weights ranging from 55 grains (3.6 g) up to 115 grains (6.8 g).

The American ammunition manufacturer Hornady got the 300 Precision Rifle Cartridge [15] SAAMI-standardized in 2018. [16] [17] In 2019 it got C.I.P.-standardized as the 300 PRC. [18] The .375 Ruger cartridge has functioned as the parent case for the .300 Precision Rifle Cartridge (300 PRC), [19] which is essentially a necked-down version of the ...
Newton recommended loading 100 grain (6.5 g) bullets at 2,800 ft/s (850 m/s); but Savage Arms reduced bullet weight to obtain a velocity of 3,000 ft/s (910 m/s), making it the first American cartridge capable of that velocity. Achieving that velocity may have been the reason for the choice of the light-for-caliber 87-grain (5.6 g) bullet. [3]
The .22-250 Remington / 5.7x48mm is a very high-velocity, short action, .22 caliber rifle cartridge primarily used for varmint hunting and small game hunting.
