Using a scope to estimate Distance

[RockyMtDan]

Anyone have any advice on using your rifle scope to estimate distance? I have seen references to this in print and other places on the net but never heard exactly how it it done.

Typically when folks refer to using rifle scopes to range an object, they are referring to mil-dot scopes or BDC scopes. Mil-dot scopes are gulated so that the distance between dots is 3.2 MOA, and if you have an object of known size, you can measure how many mils it subtends, then calculate how far it is from you.

A standard Leupold can also be used to estimate distance using the distance between the crosshair and the taper of the duplex reticle, but I cannot remember the exact method. This method is explained in the owners pamphlet that comes with a Leupold scope.

I'm still getting used to my Leupold VX-III with the varmint reticle, but you're right... the Boone and Crockett reticle may be easier to explain - it is designed for an average buck - the backbone and brisket will fit in between the crosshairs and the first elevation dash at 200 yards. If it doesn't, you are farther out... aw heck, read here:

Do your homework. Its harder than using a range finder, but I dont run on batteries. You can get as fancy as you want. My next purchase is a angle cosine indicator. The mildot master is the best investment Ive made in years.

I guess with different peoples eyesight it would differ but my main deer rifle has a Simmons 44 mag with an adjustable objective. It goes from 50 ft.-300 yds. and past that goes to infinity. I find that if I turn the objective till I get a crystal clear view it's right on the money. Up to 300 yds. that is.

I haven't found the parallax adjustment to be in best focus at the proper setting for the distance. It's parallax free when adusted, but not always in focus (that's what the focus on the eyepiece is for...).

Your focus and eyes may just work out that way on your scope, though.
