The magnums have an advantage with regards to velocity helping expansion and flatter trajectory. The problem is that this advantage is small in the real world and massive in one's head. I have gone back to the '06 myself to help control my "mental magnum".
I have killed my share of elk at 450++ with magnums so I wont tell others how far to shoot but sooner or later Murphy will school you. I decided to be more conservative with my elk shooting before this happens, now antelope is another story.
