The 220 Swift and the 22-250 can shoot the exact same bullit, same diameter, same length, same weight, same aerodynamic properties.

www.winchester.com You can see the differences in the muzzle velocity and the downrange velocity changes in these 2 cartridges here. You'll notice that the 22-250 has a higher muzzle velocity than the 220 swift, but the 220 swift has a higher ballistic co-efficient on its bullet, meaning it's more streamlined, so when downrange, the 220 swift will eventually have the speed advantage.
