Recently we picked up an older 30-06 F.N. deluxe Mauser with a detachable Pecar Scope. this rifle appears virtually in unfired condition. The objective is to load it for Tahr and Chamois . Range out to 300 + at reasonably high altitude 3000 to 6000 ft and generally shooting angle to 30 deg + or -. . any way nailing these guys is important because they can be impossible to get at if they take off wounded and ruined meat. am looking at Hornady 165 grain InterBond or SST, Speer 165 grain Grand Slam, or Nosler Ballistic Tip. Assuming these rounds are still current. we can get Sudden high winds in these areas so the more stable the bullet the better. A by product being Red Deer, Primarily Tahr is the target as tahr are akin to lamb on the table. Wild meat is getting down a bit as we finished the wild pork and Fallow deer about a week ago. Would appreciate any advice . I want a bullet which will hit hard and expand. Ancestor.
