Went out with my buddy couple days ago coyote hunting. After the 1st stand i wanted to check the long range dope i have with my Ruger Mk III/2x Nikon setup for long range plinkin'. The Nikon has a plex reticle that subtends 20 MOA from reticle's center axis. We shot at 100, 150, 175, 200, 300, 350 and finally 400 yds. and it's just amazing what can be accomplished with a decent 2x optic at longer ranges with a 22 pistol. The Nikon has 120 MOA rated in the turret [the most turret travel of any LER optic that i know of] and this rig nets me 140 with Burris Pos align rings and a total of 60 MOA forward tilt in the rings [shimmed]. From 50-yd. zero I used the reticle out to 175 calcd. at--

75=10%
100=30%
125=50
150=75
175- plex post tip

I knew that 50 gets me about 300 and ~90 to 400, and it was very close to that dope for all ranges out to 400. A couple of the shots were dead nuts very close to the aiming points [mostly cow pies]. I could actually see the pie plate sized gray cow pie 400 yd. target no problem against a light prairie grass background, and could also spot my hits from the small dust cloud impact signatures fairly well. Was quite surprised how easy it was to consistently interpolate between 20 MOA stadia points along the plex reticle out to 175 yds. as noted above. 5-7 mph winds from 6 o'clock. Don't have any field pics but here's the rig i use--
