which is easier to calculate: MOA or MILS?

[QUOTE=JeffP40;721399]I don't know of a way to range without at least an estimate of target size. You have to have something to give you a value.QUOTE]


I understand. that makes sense

if you have time to take a measurement, there is a way to fairly accurately range without target size. a topo map and compass work if you do your math, but that's an angular measurement as well.
