A 308win would fit your criteria nicely. Little less kick than a 30-06. Thinks that make a big difference is a nice recoil pad. Limbsaver, sims, several out there. Also, there is several reduced recoil loads out there. That would would fine for you.

A muzzlebreak works, but I don't like the loudness, that scares me more than the kick ever would. And its expensive to have one put on.
