How serious of competition?
I'll probably get savaged for this, but if the guy just wants to go to the range and punch paper with the kids, Remington Corelokt will shoot some pretty amazing groups in some guns. I have a 30/06 that will put 3 180s into 1/2" or less.
If those don't shoot for him, I'd try Federals with the Nosler ballistic tips.
