Thanks RR. I used to be a math teacher. Some of that stuff appeals to me.

I would LOVE to see a youtube of you setting the scope as you described.

I was given a scope recently, after the passing of Mrs. Fan's uncle. Wondering if it's any good. It's a Simmons ProSport 6-18x50 A/O Riflescope (Matte Black) . Here's a link to one site's info on it. http://www.bhphotovideo.com/c/produc...18x50_A_O.html

I haven't mounted it on anything, as I only have one big game rifle - my MOssberg 30-.06. Any feedback would be appreciated.

Thanks for all of this!
