Would a nikon m-223 or P223 work for a 308 rifle?

I just bought a remington 700 in 308, and am looking for a decent scope. I want to be able to shoot out to 600 yards. I was looking a either the nikon m-223 or the new p223 3x9. Would these scopes work with my 308. I have read that you can use Nikon's spot on. Or does anyone have any other ideas for a tactical scope that won't break the bank.

Why use a scope that's optimized for.223 on a.308? Especially when Nikon manufactures the M-308?
I don't think you'll encounter any problems with construction & design, but.223 scopes are ballistically matched to that particular calibre (see G&A's review below). There's a good chance you'll have to adjust the reticule's elevation to an extreme setting at longer ranges in order to compensate for the flight trajectory of a.223 for which it was designed in the first place.
Good alternatives IMHO are the inexpensive Millet 4-16x50 TRS-1 or one of Nikon's Monarch series.
