The numbers have already been explained so I wont go into that. I have had a Leupold Wind River spotting scope for 4 or 5 years. Wind River was the low end line of Leupold scopes when I bought it. I paid something like $230 for it, it is really close to this one: http://www.midwayusa.com/product/268...-armored-black
I can tell you that they are worth their weight in gold if the eyes are not what they used to be. I went to the the range yesterday to sight in a new set of back up sights for my AR. It was going to be a quick trip cause I only took the one rifle with me. I took every thing I needed EXCEPT
the spotting scope. I started out shooting at 50 yards to see where I was hitting. Even at 50 yards, I could not see the bullet holes so I had to walk to the target every few shots to look. I would fire 3 to 5 shots and walk to the target. What a pain in the a$$, I probably made 30 trips to the target. When I got it hitting where I wanted it, I moved to the 100 yard target and after three times of walking to that target, I finally decided that my groups were good enough.
The point of my story is that IF I had my scope with me, I could have stayed at the shooting bench and would have never had to leave it to check the targets. I learned that next time I will put the scope in the car before any thing else.
