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.

| - 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. There are no dimensional or ballistic differences between the 5.6x57mm round and the 5.6x57mmR round, other than that the latter is rimmed. The 5.6x57mm cartridge case has a distinctively thick case wall, and this causes significant problems when handloading, owing to the force that needs to be used through the press when re-sizing the case neck. It has been suggested that this unusual neck thickness is the result of the use of .22 rimfire chamber adapters in centrefire rifles chambered for this cartridge.
