I would like to be able see well enough with my old tired eyes to shoot 600-800 yds. The ability to make it to 1000 yds would be nice but really, even for fun I doubt I would do that more than once in a great while. I will eventually spend the bucks for a really good piece of glass (for both rifles) but for now, I just want something that will hang together and get me out there while I get the rifle to the point serious glass is a final expense. Hope that long winded explanation helps....laffin.
