My .308 Ultra likes Federal 150 grain Nosler ballistic tips. I know, not cheap. I tried some cheapo Sellier and Bellot ammo that was nothing but trouble. About half of the shells would not eject and my shot groups were all over the place. I would be cautious about the Wolf ammo, as well. Since then I have shot Fedreal, Remington, and Winchester without incident. I wonder how the US military surplus ammo would shoot and if it would eject.
