Commonly used "come ups" are as follows:
100-200 2 moa
As you can see with .5moa per click, to reach the 600 would require 36 clicks. As for 500 would obviously require something less, but as mentioned dependent on the ammunition ballistics. Don't shoot at 500yds always 6 or greater but if you have sight in shots first couple rounds will tell you right away what your rifle/ammo combination would require.
At 500 would estimate using some 8-9moa from your 300yd. zero?? There are graphs, charts that gives you numbers for this range, but seldom are they exactly on the spot, only shooting will actually determine the best elevation. Keep in mind that at 500yds. one MOA is equal to some 5". Run your aperture up the estimated 36 clicks and check for wobble on the rack being extended up that high. Super match, Super Duty Match, etc., etc., is no assurance that the rear sight was given the needed attention to be positive in it's adjustment and you need to know that prior to the match, just a suggestion.
