But all four are well capable with the right loads to go from 0-500 yards without an issue of trajectory or ft lbs of energy. There's not much of a debate on which is best. If your going to shoot a lot of stuff around the 500 yard mark would be hard to deny the magnums holding the better ballistics. But beware of buying a magnum in cheap light weight guns they will punish you in recoil.
What he said.
I think most of the 500+ yard shots are more of a TV advertizing stunt than actual hunting.
Just about every extreme range shot that I see on TV, they will then pan the camera back to the shooter's location and I'll think "Why didn't they sneak up to that next ridge, cut the distance in half, and make an easy, almost sure shot?"
