 With a factory-load velocity of with a 74-grain, cone-pointed bullet, it is approximately faster than the .220 Swift cartridge firing a bullet of equivalent weight.The larger case capacity means that handloaders can produce 50-grain loads that, with velocities in excess of , will outpace anything that can safely be achieved by the Swift.The .223 Winchester Super Short Magnum is a 21st-century cartridge that is comparable to the 5.6×57 mm.
