Out in the open? Something heavier, varmint profile barrel 20-24" inches with a larger scope, chambered in something fast, from .22-250 to 7stw, (.243, 6 creed, 6.5 prc/leopard, .264 win mag, .270wsm, 7 rm, and stw) suppressed where legal, with a swagger bipod, either a big horn or savage action cuz I seem to hate barrel life, adjustable stock. In closer confines? R1 .270wsm cranking something heavy and nasty with a 2-7 or 3.5-10 power would get the pick, followed quickly by a .375 ruger same scope, and crf.
