Quoted: Mil dots only work at 10 power. So the variables with mil dots have to be set to 10 in order to actually use the mil dots. |
I may be completely off in the deep end here, but the way I understand the way mildot works on variable scopes is there two different types.
First, the mildot that adjusts as you change the focus. I've never seen one of these myself, but in theory, the mildot should be able to be calculated with the default formula for distance at any zoom level. (est height * 1000 / mildot height = distance).
The second type is one where the reticle doesn't change with the zoom power. This is the type I've seen most scopes use. On this type with mildots, there is usually a marked level in which to use the standard formula. For example, it looks like Bushnell is based on 12x. (
Bushnell mildot instructions). The way it'd have to work is the reticle is sized for that zoom level to calculate the range. There is no reason I can see that it'd have to be set at 10x, as long as 1 mil = 1 mil.
One benefit for using a variable power scope with mildots is you can always change the zoom level and multiple the distance by (zoom / default mildot zoom) in case you have issues finding a height reference point.
The only scope I have with mildots is a 7-21x, with a marker at 14x. Based on tests at the range, it is working as intended at the 14x zoom level.
I may be completely wrong in all this though. If I can, please explain in more detail why it has to be 10x.
