It really depends on maximum range potential.
Shorter range shots don't need the flat shooting rounds such as the 7MM Mag. Longer range shots do.
Larger calibers do better creating larger wound channels.
Smaller, faster, lighter rounds are better for longer ranges accuracy wise.
There have been issues with small wound channels and lack of ability to track & retrieve a kill at shorter shooting distances.
You can compensate a smaller, faster round with a lighter skinned or lighter weighted round to 'open up' sooner at shorter range on thin skinned animals such as Whitetails.
Consult a guide in your area for their advisement. They'll give you accurate info.
