Around here the .308 is not very popular,not that it is not a capeble round.It mostly everyone mostly opts for the 30-06,270's and magnums.
In one of the 2 outdoor stores around here they have 2 offerings 150 gr cor-loks and 180 gr federal SP,not the cream of the crop rounds but will get anyone by in a pinch.

Now I myself is not a fan of the 308,blame it one my father or my first 30-06 what ever,I don't even like the other calibers made from the 308 case(7-08,243,260) but I like the necked down(280,25-06) versions of the 30-06 (or up 35 whelen,338-06).
Now the 308 has done somegood in it's life it kept a great gun going when it was dying out(Savage 99)and I'm sure if Savage reintoduce the 99 it would sell.Also the other part is the short mags are cutting in on the .308,alot of guys bought a 308 for it's carbine abblity in a light rifle,still would kill elk and moose.Now in todays market you can buy a short carbine magnum(Ruger's Frontier Rifle) and do what the .308 did but better.
As for snipers I don't know what they used and I hope I never find one pointing at me to find out.
Is the 308 dead by all means no,it will still be a good hunting round and be around for a long time.
