Dean, since you already have such good history and feeling for Savages, I'd be inclined to stay with them. A lot of shooting is the mystical touchy/feely relationship between a man and his rifle. It seems like if you believe in each other, goods things will follow. Or so it's been for me.
Anyway, I've spent most of my shooting life with th 30/06 and I have nothing but superlative things to say about it...best all around...most versatile...yadda, yadda, yadda. But the last ten years I've had a Model 70 in 270 that I love more each time I go out with it. Part of me would feel like a traitor to even suggest you go with 270 over 30/06. So I won't do it. But I will promise you that you won't go wrong with either choice. Both belong to the best of the best. Unless you plan on going after the big bears sometime soon in your life, I wouldn't seriously even consider any other cartridge...even though they are not the new, flashy kids in the gunstore any longer. When you boil off the advertising hype the old /06 and 270 are still as good as and mostly better than anything in their class. You'll never roam alone carrying either rifle.
Good hunting.
