You will notice almost all rifles intended for any degree of long range use will have brakes for this very reason. At least if they are serious and really going long. Also, in my opinion, rifle weight plays as big of a role in recoil as caliber in some cases. The 300 win case is only slightly larger that a 7 Rem weight here would be more of a concern to me in determining tolerable recoil than caliber. There is nothing wrong with going light for what you want and only out to 600 yards. Just know the rifle will be a little harder to get solid and steady and it is going to jump more under recoil. You will also most likely experience more barrel whip from the light tube. That means the rifle may be a little more selective to what load it shoots accurately. So be prepared to try a few different factory offerings. You might want to look to see what is available for ammo, and cost of it, even before you buy the rifle since you are going to shoot factory. Thus, one of the reasons I offered you considered a 300 win.
I took a little 13 yr old girl out last year for her first elk. She had never shot my rifle. I had her dry fire on the bedded cow a few times first then she went for it. Stoned it cold in its bed at 601 yards. After, I asked her how the recoil was on the 300 win. She said it didn't seem like it kicked as much as her 243.
