Six of one, half of a dozen on the other in terms of caliber.As you can tell from the responces here, there are advocates for both rifles. I happen to have owned both an A bolt (30-06 which I gave to my son in law) and a Rugar (7 Rem Mag which I soldto a brother in law) and loved both of them.I would stick with what you already have, and if I were to buy another rifle, I would moveway up, or down, in caliber. In my instance, I moved down from 300 win mag to .308 and my next rifle will be either a .223 or a.243 and will mostly be used for varmits. Or, as Moose said, buy better glass - either a scope, spotting scope, or binocs.

Oh, and I bought a Weatherby Vanguard SMOA and happen to think it is better than either the Browning or the Rugar (but that is just my opinion - rifle to shoulder, cross hairs on game).
