Stork, have you looked into the .358 Winchester? The short action works for both .308 and .358, saving a little weight, if that's a concern. Same head size, and bullets up to 250 grains, although OAL is limited.
BTW, if you already have an '06, why do you need anything heavier for overgrown deer? I'd take that action and build a 25/284 or something exotic like that. But that's just me! :grin:
Enjoy your time reloading, it opens up a whole new world to you. Just make haste slowly and start your charges well below max, and you'll go to your grave with all your original equipment intact. Replacement parts are hard to get at any age! :shock:
