One thing I've learned in using a 338 Win Mag load I got from Mule Deer, the amount of powder has, in my case a significant, an effect on the amount of recoil. Meaning to say, look at the loading manuals for whatever you choose and look for a powder that is max loaded at a noticeably lower charge weight. Might not give up that much performance, but will reduce recoil.
Back to my 338 experience, the 72gr 4350 loads recoiled noticeably more than the 65gr R15 loads. Never chronographed them, but according to the books I was only giving up 50fps with the lower recoiling load.
