Check out Chads bulk .308, dallasreloads.com.
I'll give another recommendation for that. I shot a few hundred of the 168gr Amax bulk when i first got my 308 barrel. It was consistent and very affordable. Wasn't the most accurate off the shelf ammo for me, but it was by far the cheapest and what i deemed to be the best value. Did better in my particular rifle than the most affordable "good factory ammo," the Federal gold match and hornady match series.
