How many clicks

I have a super match which I have zeroed at 100 yards. I am shooting a 500 yard match April 1. Can someone give me an idea how many clicks I need to elevate to be in the ball park? I am using the national match iron sights that came on the weapon.

What ammo?

Thanks from SGT John SWF

Commonly used "come ups" are as follows:
100-200 2 moa
200-300 3moa
300-600 10moa

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.

Standard NM rear sights have 1 moa ELEV change per click - unless your's has a 1/2 moa 'disc' between the elev knob and the receiver (unlikely).
Rotating the hood gives 1/2 moa change (notch DOWN is 1/2 moa lower than notch UP).

For any typical cartridge with 145-175 grain FMJ or HPBT bullet, I'd start with 13 clicks UP from the 100 yard zero. You'll definitely be 'on paper' and probably 'in the black'.

13 clicks should get you on paper.

Having re read my posting on this subject I see that I was in error. I tend to think of a micrometer rear sight system and my using 36 clicks would put you closer to 1000yds. than 500, definitely high. I forgot that the M1Garand, M14 sight elevation is done in full 1moa/click and the half minute for elevation is a function of the hood rotating. As so well pointed out, 13 clicks from your 100yd zero should be pretty much spot on for 500yds. I typically would dial in 15moa/clicks for the 600yd. target to start. As my dear mother used to say, "I stand corrected." The disc was mentioned and I have a bag full of those things somewhere and did attempt to use them once, but found the .5 side(mine are two sided, other being 1moa) and the serrations for the elevation drum to contact were so shallow it was easy to roll past a few in doing so. I don't need them nor use them and if I can find the little buggers will offer them up to those who want them and you can't beat the price, free. Now if I can just find them and when I do will post accordingly.

Some additional info about 'come ups' on M1 and M14 rifles.

Even if you haven't calibrated the ELEV drum for the drum marks to match an actual 'zero', you can still use the number of clicks on the drum to tell you approximately how many clicks are needed from one distance to another. Just move the drum to read your starting distance and then turn and count clicks to the desired distance - that number of clicks is the come up/down from the start to the desired distance. Then put that number of clicks on your ACTUAL elev setting for the start distance..

The number of clicks on the drum remain the same, regardless of whether the drum has been calibrated or not!
