My 2 cents, 338WM in the right gun
Percieved recoil has many inputs that all add up to the sum, cartridge design is just one.
Bullet weights, speed, rifle weight, stock design, recoil pad, size of the shooter and even the clothes he's wearing all have a part in what we percieve in recoil.
I had a 300WSM that was a pussycat, my buddy's 300 WSM with the same load would tear your shoulder off.
The only thing I noticed with the 300WSM is most rifles carry one less round in the magazine.
Any caliber mentioned above will do what you ask of it depending where and how you hunt.
If your a walker / stalker in the bush you can only carry one gun, you will not have the luxury of deciding which firearm to respond with. Should a big furry b@stard pop out and decide your lunch (he won't care that your not hunting him, he's decided to hunt you.) what would you rather respond with. A 338 with 4 shots or a 300WSM with 3 (or 2 in some)?
For me, I sold the 300WSM and went with the 338WM, but I still have a few 300WM's and a 6.5x55 for the less dense, vehicle friendly adventures.
