Hmmm you better have a big wallet. Cause your gonna like spending the money once you start.... Any of them listed should work good for deer out to 500. Just be prepared to spend a lot of time at the range. Buy the best glass you can afford. do not go cheapon a scope or range finder. There is a lot of things you can do, like glass bedding, muzzle breaks, different barrels.... go check out a forum called "longrangehunting.com" It is full of information.
