What cartridge, bullet, velocity ?

Easiest and best thing is shoot at 200 yard dirt berm with your 100 yard setting. Note the strikes position vs targets position you have the answer 

Use something easily seen, orange clay target, tin can whatever and have an elevation reference point.  How high is a nearby  target frame, no frame use a measured 2x4 stake

Our club's 200 yard match with spotters we get zeros for new shooters in 3 or 4 shots. If the shooter does what he's told and knows how to adjust the sight.

At 25 yards its 7 inches high and you should be on the 200 yard offhand target.
from 100 to 200 I think its 14 inches. that's a guess.

Add more,

Shoot one shot it strikes "about" 2 feet low. At 200 that's 12 moa. Raise sight 12 moa.  2nd strike it's a "little bit" low raise 2 more moa. 3rd strike it's "real close" that's enough berm shooting .

Real close to what you want, go to a paper target shoot a group, 2 shots is enough, measure the center of impact vs Bull and make the precise adjustment, you'r home with the exception, bench and offhand zeros are not the same. Couple of MOA difference depending on the gun and how it rides on recoil.

The amount of correction will depend on the sight radius. The shorter the sight radius the greater the shift in POI per adjustment increment.  The longer the sight radius the less POI shift per adjustment increment.

True, sight radius is significant  factor. My two CPA's 28 inch barrels with MVA & Mike Stevens tang sights move 1.25 MOA per graduation. Individual rifle ranges will vary in actual distance firing line to target too.  Another reason to prove your own distance adjustments 

Three ways to obtain sight settings. Calculation, asking someone else, observation, your rifle your loads your ranges distance.  Observation the fastest and most reliable.

Correct but now if one of those rifles had a 34" barrel or more correctly a longer sight radius it will require a greater amount of adjustment to equal the same POI shift as your 28" barrel. 
I dont know if I am the only one to ever catch this in the movie Quigley Down Under but when he is describing his rifle to Mr. Marshton  he says two thing that can not both be true.  First he says the usual barrel length is 30" but this one has an extra 4".  Then he says about his sights that it is marked up to 1200 yards but (and here it is) this one shoots a might farther. NO !! That is exactly wrong.  That extra 4" of sight radius would be dropping rounds short with the same sight setting as with a 30" barrel. Yes little things like that in movies bug me. The whole reason for the longer sight radius for long range target shooting is actually for that very reason, because slight movements in aiming have less affect on POI shift than with shorter barrels.
