The .300 magnums and .338 are not to far off what you have been experiencing with the 12ga in terms of recoil. You had mentioned about barrel burn out. It would take consistently shooting hundreds and hundreds of "hot loads" to wear out today's manufactured barrels. Throat erosion would probably happen faster than barrel wear would. A 30/06 as others have mentioned will be the best for you if your concerned with recoil. If it bothers you that much there are systems available to help reduce "felt recoil"
Thanks. I believe I've made my mind up (30-06). Now to choose the rifle. Wood stock is a must, and preferably around the $1000 or under mark, although I might go 1500 for something that's got a great reputation.
