You mentioned a budget of up to 700 dollars. The 3-15 SS accomplishes a major % of your requirements within budget, and brings you up to 1k yard range when you are ready -- and may even keep you company for a few years until you decide to go with something else. Some of the other suggestions probably will do so as well.

I personally would not want to hunt with a 10x fixed.

To be honest, I'm not sure why you are chaining yourself w/ a 600 yard chain, when we live in a state with plenty of LR options. I would advise against getting some hybrid/low-ball scope no one really wants aftermarket as well. You're either planning to sell it or keep it, so get something you want to keep and which is a little easier to sell.

At the end of the day, you can do a LOT with some budget equipment. And really, you could probably do just fine with a 10x SS, but I don't understand the desire to compromise on all counts. A "hunting" scope will not be a good tool for LR precision shooting, but a LR precision style scope will be fine for hunting.
