I have a Ruger American in 30-06 and I'm looking for a good 400-600 yard scope for (don't laugh me off the board here) under $200. I'm obviously not looking to set any distance records, but I'd at least like to be able to consistently hit a paper plate at somewhere around those distances. Also, is it just as important or even more so to focus first on a good set of rings? There's so much stuff out there to choose from, I have no idea who makes the better equipment these days.
