IMO a magnum is a excuse for poor hunting skills for SOME .
I am to lazy to get any closer or I can't tell 200 from 400 so I will just shoot this big BOOMER

Some like the amount of blood shot meat they get
Others it is a ego thing ,mine will shoot farther and faster than yours

I shoot a 257 AI for deer and a 338/06 for anything bigger.
I have never had to shoot a deer or anything else farther than 300 yds so I see no need for a magnum.
