Just a few quotes from Nightfoce Reticle information , that may help you out
"Ranging Power Ring Settings
If your riflescope has a ranging reticle, the power setting for using the ranging features at their listed spacing, may be marked with an “R” on the power zoom ring. If no “R” marking is found then set it to the corresponding power zoom setting as shown in the chart below.
All models are calibrated to give the specified distance spacing at the following power zoom settings:
1-4x @ 4x
2.5-10x @ 10x
3.5-15x @15x
5.5-22x @ 22x
8-32x @ 22x (R)
12-42x @ 22x (R)
Ranging
Any reticle that has at least two reference points of a known distance in M.O.A. or Mils can be used for range estimation to some extent. One of the easiest reticles to understand is the NP-R1 with its 1 M.O.A. spacing between the vertical stadia tic marks. If you know the size of your target then you can use the M.O.A. spacing between points on the reticle to estimate the distance to your target. You can create a reference chart that lists the type of targets or game you will be engaging and their M.O.A. size at the various ranges you may encounter them.
Example – 20” high target using the NP-R1 reticle with the power zoom ring set at the ranging mark.
At 100 yards this spacing will fit between 20 lines on the vertical stadia. 200 yards - 10 lines 300 yards - 6.5 lines
400 yards - 5 lines 500 yards - 4 lines 600 yards – 3.3 lines 700 yards – 2.9 lines 800 yards – 2.5 lines 900 yards – 2.2 lines 1000 yards - 2 lines
You may change the power zoom ring setting to increase the M.O.A. spacing between marks on the reticle. Halving the power doubles the distance. For example with the 5.5-22x the spacing is 1 M.O.A. between the horizontal lines, at 11x the spacing becomes 2 M.O.A., which will allow you to range larger or closer targets more easily.
Even a very simple reticle design such as the NP-1, can still be used for limited ranging of some targets. The distance between the cen- ter of the reticle and the beginning of the thicker line at the 6:00 position is 2 M.O.A at 22x. This could be used to range a target that was 20” high at 1000 yards. By changing the power zoom to 5.5x the spacing becomes 8 M.O.A., which could be used to range a 16” targetat200yards,a 48”targetat600yardsoran80”targetat 1000 yards.
You can customize your reticle subtension at desired power zoom settings for your Nightforce scope by utilizing the custom feature on our Nightforce ballistic software.
For a more detailed explanation of using various points on the reticle to estimate range to the target refer to the NP-1RR reticle on page 2.
