At the risk of be flamed on this forum, if recoil really is an issue (which it sounds as though it is), send your rifle out and have a brake installed. look at
http://www.muzzlebrake.com/index.htmlfor some quality work at good prices. Kevin did my 300 RUM and tamed it to about that of a270 or less. This would give you the caliber you want and fix your recoil problem. Noise level goes up for those around you, but they sure work.
