Well, a few months ago when I wrote the last article, I had a few tests I decided to run at our spring Precision Optics Workshop and the great folks who attended were all willing guinea pigs.
In the previous article, I postulated that the ability to accurately estimate the range to a target using a graduated scope reticle would be limited by the capabilities of the human eye, and that capability would be somewhere between 1 and 5 arc-minutes, but I didn’t exactly know where to set the bar.  My best guess, given glass quality and atmospheric effects was about 2 arc minutes.

To test this, we played a little game with 10 participants.  5 “shooters” with optics greater than 20X and 5 “shooters” using optics less than 20X.   The scopes used were a fairly representative sample of the common glass out … Read More »
