Or you can get the biggest meat wrecker your wallet can handle if ya don't mind retrieving your game with a mop and a bucket. If you need to take shots at elk from 400-500-600 yards and farther then you need to learn the art of calling, or your way to noisy, or not paying attention to your wind. Getting back to the original question, shoot which ever one fits you best and gives you the most versatile range or rounds. I prefer the 300wsm and have dropped every thing from trophy mulies and white tails to Canadian moose without having to look farther then where they stood when I pulled the trigger.
I agree with a lot of what you're saying. But, I would put a different spin on it.
Since we don't discuss ethics here, I can only speak for myself. But, if I was into LRH and wasn't setting out to call an elk into close range, then I'd simply feel more comfortable with an extra safety margin. i.e. bigger cartridge
Regardless of the cartridge, I would expect myself to be 99.9% certain of hitting the vitals under the actual conditions at the time.
If you simply don't like recoil, then weight and brakes will solve the problem. So, there's no excuse for being under-gunned.
It's all relative. If 7RM won't reach out far enough to your liking, you either need faster mv such as 7STW with the added expense of ammo and barrel life. Or, you need to step up to 30 cal or 338.
I put a 300 WM barrel on my Sendero and my 15yo son shot it just fine. Once I stick a brake on it, I expect he'll be shooting 20 shot strings without hesitation.
