*1/1000 inch bullet diameter *16/1000 inch neck diameter *16/1000 inch base diameter *16/1000 inch rim diameter *365/1000 inch case length *457/1000 inch cartridge length and depending on the powder used, the 22 Winchester Magnum Rimfire can have almost twice the muzzle velocity and muzzle energy as the 22 Long Rifle.
