5mm Remington Rimfire Magnum (5 mm RFM): a .20 caliber rimfire cartridge that is based on the .22 Winchester Magnum Rimfire case, it has greater muzzle energy, longer range, and a flatter trajectory over many of the other rimfire cartridges, uncommon but still available.
The .223 WSSM was introduced in 2003 by the Browning Arms Company, Winchester Ammunition, and Winchester Repeating Arms Company. The .223 designation is a reference to the popular .223 Remington . It is currently the fastest production .22 caliber round in the world with muzzle velocities as high as 4,600 feet per second (1,402 meters per second).
Originally, it slightly outperformed the .22 LR, but was "not noted for great accuracy", [2] while later smokeless loads achieved about the same muzzle velocity as the .22 LR. [citation needed] As with the .22 Winchester Automatic [3] and .22 Remington Automatic, [4] the .22 extra long will not chamber correctly in .22 long rifle weapons. [2]
