Another thing to look at in a budget minded situation is your reloading cost. It seems that the 300WSM would fit what your wanting to do nicely and be cost effective to reload thus more trigger time. And if you are rock'n a Savage you can roll on a 300RUM and lay the smack down when needed.
I would build a 300WSM on a long action Savage with a moderate contour, heavy on the fluting in a light stock for a nice walking stick and for doing a lot of shooting on steel, then roll on a heavy, braked, long 300RUM and drop it in a more tactical style stock with a couple recoil reducers in the butt stock for when the long range heavy hitter is needed.
It's a Savage rock it how you need to
