Over gunned is a matter of opinion. Would a 3006 be considered too much? If not WHY?
I have shot deer with a 338. Too much maybe but it worked just as well as the beloved .270 (in fact produced less bloodshot or waste). For me I just wanted to see what my elk/moose load did on a deer sized critter. Likely never use it again b/c I have other options to chose from for the task. In my region many guys hunt antelope to moose with only one rifle to choose from and what my be overkill on one species might be under on another.
