It would be difficult to apply that reticle as a holdover reticle--there r too many uneven stadia points in it. It could be calcd., but it's just way easier to use the NP-R1 or 2. I didn't realize the NP-R2 had 5 MOA windage units. That is a little large to interpolate accurately. I would then stay with the NP-R1. Ranging with it's simple. It's based on the mil-ranging formula using 1 MOA (1.0472 inch per 100 yds.) subtension unit--
tgt size (") x range of reticle subtension measurment (usually 100 yds.) / reticle subtension (") / "mil-reading" (decimal equivalent) = range yds.
...looks complicated, super simple to apply. I use 11" back to brisket for a coyote. Suppose the coyote occupies 3.5 1 MOA subtension units, then just fill in the blanks--
11 x 100 / 1.0472 / 3.5 = x
So that entry on your range sticker would be--
...i calculate reticle-rangefinding to about 500 yds. as that's about as far as i can expect to get good results most of the time.
Here's what my reticle ranging looks like for an 11" coyote using the 1/2 mil units in Darrell Holland's Ultimate Mil reticle. I put it on a sticker and place it in a Butler Creek Blizzard-style objective cover. The Blizzard can be disassembled from the inside. It's almost like it was designed for just this application--pretty slick really...IMO.--
