With a factory-load velocity of ft/s ( m/s) with a 74-grain, cone-pointed bullet, it is approximately ft/s ( m/s) 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 ft/s ( m/s), will outpace anything that can safely be achieved by the Swift. There are no dimensional or ballistic differences between the 5.6x57mm round and the 5.6x57mmR round, other than that the latter is rimmed.
