2. Figure out which loads you want to shoot at long range and then call the Leupold Custom Shop (1-800-LEUPOLD) so they can make you a custom dial. Provide them with the diameter, ballistic coefficient, bullet type (spitzer, round nose, etc.), muzzle velocity (it helps if you have a chronograph so you can give them what you're actually getting), the average elevation and temperature at which you shoot, and whether you intend to zero the gun at 100 or 200 yards. The price is $50 per dial.
