SFP Mil Dot Reticle Subtension Calculations

Recommended Posts

Modern tactical scopes are very new to me, I dunno if my terminology is correct but here goes. 

 

If a sfp mil dot (or moa) reticle is only "correct" at it's highest magnification, for example a 4-12 is only correct at 12x, would it be safe to assume that two dots at 6x would be equal 1 mil?

Okay, so let's assume my scope magnification values are actually 4-12 power, not the rounded off retail packaging values found on many scopes.. 

 

If I zero the scope at 100m on 12 power, then dial it back to 6, and move the target out to 200m and hold the crosshairs on center of target, where will the poi be?  Will it be one dot under the crosshairs?  one dot being 1 mrad which should equal 10 cm under the target center.

 

btw, the scope i'm currently looking at is a Leupold Mark AR 4-12x40AO.  Oddly enough, the actual power of the AO versions in this scope line are the actual power. 

 

Yanno...  the more i think about this the more i'm thinking i'm going to go with a moa/moa scope instead.  the conversions are killing me.

This question can't be answered without knowing the ballistics of the ammo used.

 

A mil is a meter wide at 1000 meters and one centimeter at 100 meters. You are not going to solve your problem with a moa scope. If you're using a mil dot scope think metric; if you're using a moa scope think English system. No conversions needed then.
