Rifle Scopes How to take distance measurements with mildot SFP

[johnsta]

Hey guys. Sorry for the beginner questions.

I have a Leupold Mark 4 6.5-20x50 scope with their mildot reticle. Since it is a SFP scope, at what magnification power should I take the mil measurement at? Let's say I measure a 12 inch target with 1 mil. That puts the distance at about 333 yards. Well if I change the magnification and it measures .5 mils, than it is a distance of 666 yards. What is the universal magnification power on the SFP for distance measurements on my mark 4? Man I really wish I had a FFP!

Sorry if this is a dumb question, I am a beginner. Thanks for your time!

I know at least some of the Leupolds you take the measurement at max magnification.

If I remember correctly Leupolds are designed to subtend correctly at max magnification.

Generally, the ranging power on an SFP scope is its highest magnification. Even if the mag ring indicates you're on a certain power though, it may not be exact and that will throw you off. You can do something like sticking a yard stick exactly @ 100 yards (have fun measuring that) and see if it spans 10 mils.

Ok thanks guys. I will give it a try on 20x to see if it is accurate.

^ ^ ^ ^ what azimutha said using the yard stick or other precision measuring device, but with one additional tip: ensure the range to target is EXACTLY 100 yds.

To be precise, the distance measurement will be from turrets to target. Do not depend on a LRF reading or the local range saying "it's a 100 yds". Get a tape and measure the distance yourself. Now check your Mil scale at full power and ensure calibration, or find the point. At this time, you can also find the "50% point" of calibration if you think it might be helpful.

Good Luck,
