help request- targets for sighting in rifles

I am interested in making some simple targets of my own for sighting in rifles/scopes.
Does anyone know the ratio of size of the dot and distance between them to create targets for different range zeroes?

For example, this target will have 2 dots on it: one inch diameter each, and one directly above the other with one inch distance between the centers of each dot (thus, the edges are touching; half an inch from each dot). This will put my zero one inch high at 100 yards, or so the original creator of this target says, if this target is set up 25 yards away. OK????

What I would like to do is be able to create targets that I can set up at any range I want, specific to each target of course. So maybe I want one that is designed to give a dead-on zero at 100 yards, if the target itself id placed at 3 yards away; or one that gives a dead-on zero at 400 yards if the paper is set at 17.39487 yards away; or whatever.
Basically i want to know how to create all possible combinations.

Can this be done? Can any rifle expert help educate me on this project?

A million thanks,
C-

  Being lazy, I buy 100 yard sight in targets from Rifle Magazine/Wolf Publishing.

  I also like ez2ctargets, they are great and the price is reasonable.

  If I am understanding what you want, I would have to say that it would be extremely difficult if not next to impossible to do.Each target would have to be different according to the range. Also each caliber you shoot would require a different target, the target for each load of that caliber would also be different as well, each load is going to shoot different. My suggestion is to use targets that are already available and shoot at 25,100 or 200 yards. Get a ballistics chart that shows your bullets trajectory, it will show your drop and rise at the different ranges and you can go from there.

  Dot spacing is going to depend on the bore to sight height, BC of the bullet used, actual MV, tempature, humidity, barometric pressure, wind direction, etc.
  The most accurate way I know of is to create a drop chart with your rifle (at various ranges), which has the added benifit of showing you how it groups at those ranges (and conditions).
  The easiest way is with a computer balistics program.
  Either way you need to prove it by shooting at that range
  For targets I use a orange dot over a piece of 1/4" grid graph paper (makes it easy to measure the group size and location). I do my offset settings at 100 yards, any closer and the errors can realy stack up on you.
