Elevation adjustments
Hello, new here and to long range shooting. My question concerns the click adjustments for my scope which has 1/8" increments. Is there a chart that would show the number of clicks for different ranges? I have chrono'd my final load and know what my drop is starting @ zero @ 100 yards. Thanks, smoker1

Your clicks are 1/8" at 100 yards. Therefore, at 200 yards they are going to be close to 1/4" per click, 300 yards will be about 3/8" per click, and so on.

For simplicity's sake, say your load drops 1" at 200 yards from a zero at 100 yards. To zero at at 200 yards, you are going to have to come up four clicks. At 400 yards, your clicks are close to 1/2", so if your load drops 6"; come up 12 clicks and that will get you close.

You'll have to shoot different distances under different conditions to know, but this should get you in the ballpark. Take clear notes as you shoot, so you can develop your drop charts.

Thanks MS, I thought I had it about right by multiplying the distance by .125. Seems that works out. I presently have a printout taped to my scope but it gives drop per 100 and using that for the first time last week proved a little confusing, so I guess all I want to know is how many clicks and not the drop....right?

You'll need to know the drop to determine the. Number of clicks you need to come up.

I find it easier to think in terms of Minute of Angle. Check out this video. It may be helpful to you.

Also, plenty of scopes with 1/8" adjustments are not really 1/8". I would suggest setting up a grid at a known distance (like 100 yards) bolt the scope down to something solid and start cranking the knobs. MOA is often a useful measurement, so if you set up a square of +/- 5 MOA (or 10 MOA or whatever your field of view allows) in AZ and EL then crank the adjustments and see how many "clicks" it really takes to make a given adjustment. While you have this set up you may also want to see if the adjustments are repeatable, often enough they are not. This is part of why long range shooters shell out for expensive optics, so that these adjustments can be made with precision and confidence.

Good point. I'm sure that the adjustments on my particular scope will not be precise but hair is much better than air.....right?
