One thing that has not been mentioned is the value of a spotter in wind conditions, If you are shooting alone you are at a disadvantage in windy conditions if you have an unexperienced spotter you have the same disadvantage. If you have a spotter with the same experience as you do you can extend your range several hundred yards.

With my longtime hunting partner both of us made longrange hits in the wind several times past the mile mark, my hunting partner moved on to other things. I took my lifelong best friend with me on a hunting trip last year.....took a shot at 900yards........Where did it hit ??????

Lets go home....

Those that live in the myopia of one shot one kill have a spotter that are as good as they are.....and sometimes they miss the first and hit on the second !!!!!! No chance on the second with a crappy spotter.....
