Head shot, frontal, broadside, Texas heart shot, all are lethal if placed properly. NONE are any good with a 458mag if the shot is not made properly!
I have witnessed a white tail take off after being gut shot with a 375H&H, truly a disgusting thing.
Especially after I was told that it was the best there is by the guy shooting it, and apparantly he was an "expert shot"!!
Hit them where you are aiming and all is well.
There - I'm done, C'ya!
