I'd get a vx-iii over a vx-ii hands down.

If you can afford a zeiss conquest, may want to take a look at those. It's a step up IMO.

I'd get a black scope even with a stainless barrel. Get at least a 3.5-10x

Your standard duplex will be fine, if you really want to shoot 400 or 500yds you can get the boone and crockett reticle.

Leupold makes some decent mounts, lately I've been going with Talley's.
