Hey guys!
I need some advice on what my best options are for a good scope. I have a Remington 700 chambered in .308; already have good scope mounting equipment.
I have plenty of clearance for a scope with a 50mm objective lens, and would prefer a scope with a 30mm tube (currently have 30mm scope rings with spacers for a 1" scope.. I planned ahead

). I would like something with a minimum of 10x zoom and would prefer a max zoom of around 20x-25x. I prefer a mil-dot reticle but am open to try new things. FFP would be cool but isn't necessary. I also don't really have a need for a light-up reticle, or any sort of other features for that matter.
I don't hunt.. I'll only be target shooting, in broad daylight, and I won't be toting this thing through hell and back either. I shoot in the 100-400 yard range and would like to extend my range out to 500 or 600 yards.
Here's the catch.. my budget is about $700. Stretched. And I won't have that for a few more months. I know that a lot of people say that you should save up at least $1000 for a good scope, but it just isn't possible. I really need a recommendation for a good scope that costs $700 max.. however, I'm willing to buy used.
Thanks in advance!
