Being the age that I am,my eyes aren't what they used to be.I have to have more magnification on my scopes just to see things at longer ranges.
I used to think that anything over 14-16x magnification was too much,but nowadays I'll take as much as I can get.
I have 2 Sightron SIII 6-24x50 scopes.They are probably the best scopes for the money on the market right now for shooting long range.I have a Swarovski scope on another rifle,and the Sightrons are just as good for 1/3 of the price.
IOR Valdada is also a great scope,and they offer some great reticles,also Zeiss has great optics in that price range but they lack in elevation/windage adjustment for really long ranges.
Leupold VXIII & Mark VI scopes are also great scopes,they are just priced about $400-500 more than they're worth,for what you get.
This is about the cheapest you find the Sightron's,I bought my last one from them-
