Federal Cast Core 300g hardcast bullets, leupold 2X, or a low power variable 1.5-5X or so.
Buffalo and garrets are not cheap, though nethier are the federal "cast core." All provide hard cast bullet performance with a big .340" meplat when using WFN nose profile. The federals proved to be accurate enough in my rugers for 100+yd hunting. I think they cost about 20-$25 a box.
