RE: .308 factory ammo
Go to your nearest Wal-Mart (Wally World), and buy some Federal PowerShoks, they are only $11.95 per box, and they are very accurate, they are kinda "loaded", so to speak, in fact, they shoot an inch higher than Hornady SST's!
I would really suggest the Powershoks, they worked great for my Remington Model 673 .308, and you should see if they work for you.
Just My 2 Cents.....
