Try giving Nikon a call if you want to jump on that used one and it's still available, I'm sure it won't last long. I'm sure they tell you, but I am sure they will say it is. I've never seen a scope that was rated for one centerfire but not another, it's usually only rimfire/centerfire. I think any of the choices above would be good... Tikka, Howa, Rem, Savage, Stevens... all are solid, generally good shooting rifles. I have a Remington 700 SPSV that drives tacks even with the tupperware stock that I am happy with, but it's a little heavy on stand. I was thinking I'd probably buy a Tikka T3 Lite, but I got bit by that black gun bug.
BTW posting up a price range might give you more choices, or narrow them. Good luck, I'm sure you'll be happy with any of the choices.
