I don't know the 30-06, but am a Win M70 fan. IMO, there is NO REASONABLE EXCUSE to practice with or shoot bullets at North American game through rifles that deliver pain to the shoulder of the shooter. How does that HELP your confidence and accuracy when shooting at game? Does it really matter that the bullet got to the target 0.0123 seconds earlier? (I made that number up). Does it really matter that it shot 0.125 inches flatter across the distance? It matters to your shoulder I bet.
My Lyman cast bullet catalog indicates these bullet weight choices [150; 160; 170; 173; 180; 190; 195; 200; and 210]. Chose a lighter weight bullet. There is NOTHING WRONG with mid-range either. These bullets will kill just as dead as heavy weight-for-caliber and you will thank yourself for not punching your shoulder all the times you went to practice.
If you eventually develop a flinch with the heavy weights, it will be there for your other calibers too. It's a mental as much as a physical thing and you do not want to introduce that into your shooting regime.
If you hand load, reduce the powder charge too. A "smoking hot fast" bullet doesn't kill any better than a slower get-the-job-done and lighter recoil on the shooter bullet does.
Remember, this is posted for discussion on the GBO DEER HUNTING FORUM where those thin skinned animals require neither large diameter, extreme speed, or lazer-flat trajectory rounds. In general, shoot anything you want, including the 460 Weatherby Magnum, et al, but it isn't necessary for N. American game.
My $0.02 worth anyway...
