Ok I would love some advice. This is going to be my one nice scope. For right now it will be on my 20” 308 ar-10. Hopefully sometime this year I will add a 300win mag and the scope will pull double duty. I can only afford one. I have EXTREMELY bad eye sight so I shoot more magnification than I should but I do what I have to. I will be shooting steel out to 800 yards and hopefully at some point have the opportunity to shoot to 1000. Thank you all for the help. Pics and links are definitely appreciated if you think it will be helpful. Thanks again.
