I'll second the Winchester Super-X for affordable hunting ammo. Shoots pretty well in my 30-06 UltraComp. From what I have heard about about Mac's former 308 it shot them very well, and other members here too.
I love Federal ammo, but it's usually a little higher.
Strange, I have always seemed to have better luck with Winchester ammo than Remington Core-lokt's. Just a personal observation.
