A second focal plane scope with a calibrated reticle such at the Leupold VX3 with the varmint reticle can be calibrated for just about any cartridge. You simply have to find the magnification that will match the reticle to the bullet speed you are shooting. Its BDC goes from 200 to 500 yards. Once you know the correct magnification for your cartridge, you must shoot the scope at that particular power. The 200 yard zero will stay a constant, but all the other range lines will be off.
