[QUOTE="sscoyote, post: 952019, member: 1133"] Here's what I assume the reticle looks like-- "E". Even the thickness of the lines can throw your estimation/calcs off somewhat. Darrell Holland and I have a theory about interpolating between stadia lines of reticles for rangefinding purposes in that people tend to guess between the edges of the stadia lines and not from the center of the line to the center of the next line. That throws the interpolation off (a lot at that distance) and now the subtension should probably be 4 MOA-.15 or 3.85. Now the equation becomes 36 x 100 / 1.0472/3.85 = 892 yds. [/QUOTE]
