The .308 is a fantastic round, and dont let anyone tell you otherwise. Dont buy into the magnum/ and or big cannon hype. I think if rocket launchers were legal, you'd see at least one knuclehead packin one though the bush ~ Just to prove he could "handle it"... And he would be SURE to have an argument on how great it was, due to the fact it not only killed game, but butchered it for him at the same time...
Generally the type that pack these monster Magnums, seem to be the type compensating for something else. (if ya get my drift) They are usually the same people that have an 84" TV, a truck that is just shy of Monster truck requirements, and a wife with more plastic in her than a lego set. (I'm not trying to stereotype, but this has been my experience ~ I'm not bashing Magnum owners... Just those that buy them so they can BRAG about their Magnum, and how much better it is... along with all the previously mentioned items)
I plan on getting back into hunting next year, and a .308 is #1 on my list to get.
My grandfather hunted his .30-30, and it sure as shoot put meat on the table.
Do magnums have their place. YES. Do you need one to hunt deer etc? Not at all. I know girls that hunt Deer with a .243 with great success. If you wanna get into Moose and Bear, then yeah, bigger wouldnt hurt.
Decide for YOURSELF, what you need. If you go into a shop and wish to buy a .308, and they say you need a magnum... walk out. Take your business elsewhere. If you've done your research, then "stick to your guns" no pun intended.
There's my 2 cents. Take it or leave it.
