A rifle scope, that is.
Just curious if anyone has tried it or has become proficient at it.
I bought a slightly used .308 last week and I'm looking for a scope to go on it. The more I research scopes, the more I am considering a mil-dot scope. I would think that using a mil-dot scope for ranging distance would be an easy adjustment for a surveyor.
Any thoughts?

A bunch of us guys get together every so often and have shooting competitions where yardage is unknown (unknown to the competitor) but the height of target is known:
Height of target in inches x 27.8 (25.4)/Mils read = Distance to target in yards (meters)
What I do is take 2 readings on my 20x scope; one at 20x and one at 10x. I multiply the reading at 20x by 2 and mean the two:
(Reading at 20x)2 + Reading at 10x / 2, then plug the mean mil reading into the above formula and viola.
The competition is scored by the target score and a bonus for how close the yardage calculation is for each position shot from. The above method usually gets me within +/-5 yards of actual.
Thanks Hub, now I have yet another reason to finally get me a smart phone.

I have been studying on the proper method and I realize it will take me a while to get to where I can do the math in my head.
I have been considering approaching it more like a surveyor would. Each mil-dot is a 1:1000 ratio so 10 mils which is from the bottom post to the top post would be a 1:100 ratio, the same as stadia hairs. Actually it would be 1:98 because of rounding the milliradians to 6400.
I'm thinking that without a calculator and just doing the math in my head, I would do better at approaching it the same as shooting stadia in feet and then converting to yards. I may prove myself wrong. If a T-post that I know should be about 4.5 feet high is at 4 dots then I'm looking at about 1125 feet or 375 yards.
I'm still looking at the difference in scopes that the mil-dots are only accurate at one magnification and the ones with the dots on the first focal plane. I won't be entering any competitions doing this, I ain't that good of shot. It's just something to play with.
Thanks,
James
