If you handload,it's hard to beat a 280 or 280 Ackley.
If you don't then 6.5 Creedmoor,270,7mm-08,and 308 are all perfect.
I think the 30-06 is perfect but does recoil more than the others that I've mentioned. It may not be the perfect deer cartridge but it is the perfect all around cartridge for North America,having kiled innumerable elk,moose,and big bears.
