If I could find a good bolt gun for it, the 6.8mm SPC would seem to fit your bill. Very mild recoil and 200yrds is about it limit for deer hunting.
The sad point is that I only see it on the AR type rifle and now Ruger is making their ranch rifle in it also. But I would want a bolt gun. But if you are happy with a semi auto the 6.8 SPC seems like just the ticket.
