Mopar92;
I'm assuming that if you're talking about putting a Nightforce scope, that you already have, on the proposed gun that's being discussed, the budget is not particularly tight. Therefore, if you want a gun that shoots right outta the box, that you're almost certainly not going to have to sink more money into, take a good hard look at the Sako TRG42 - in .300 Winchester Magnum. Yeah, it costs more than the Remmie, but you get a far more refined package for your money.
Or, if you want to do it with a more-or-less off the shelf gun, go to the non-fancy Sako, they call it a Tikka T3 Tactical. Made in the same factory on the same machinery, but less hand work & therefore less money.
Or, hang out with the benchrest guys at your local range(s) & buy a gun with a magnum boltface & have it rebarreled to .300 WM. Given good social skills on your part & some patience, this may indeed be the most economical way to go depending on what's available for sale.
