Have you considered a muzzle break?
I know your pain.
I have a Savage model 110 in 30-06 and it was brutal to shoot. I normally shot the 165 or 180 grain Core-lokt ammo, so it's got a pretty stout punch with it.
I talked with my gunsmith, and we decided to put a muzzle break on it.
WOW, what a difference. It's now a pleasure to shoot. I've been told we dropped the recoil down to nearly the same as a 270. This is now my goto rifle for everything short of elk. I have an other bruiser for them.
I was totally amazed how much the difference is with that break on it. It might be something you might want to consider too.
