You may want to investigate revamping your 300 WSM EW to a lighter platform...
I have the same M70 EW in 300 WSM. Mine has a 3.5-10x40 Leupold in X-Low Talley Lwt's. I swapped-out the steel follower with an aluminum one, and the factory bottom metal with a PT&G aluminum one. Those two items shaved 2.5 oz's. I'll be selling the B&C stock and putting it in a Bansner or Brown. All-up weight with sling and rounds will be around 7.75 lbs. RL17 sends the 180's at 3,030. It's the most accurate rifle I own, and I really like its weight-forward feel over the lighter Kimber's. It doesn't offer that much more than a 30-06, but for me it's more about the rifle it's chambered in. It's a better LR rig than the Kimber. A bit heavier and more barrel weight.
Only other thing I'd suggest is a 375 H&H.
Like me, you sound bored
