RE: Best Antelope rifle???
You can't go wrong with the 25-06 Rem great gun for lopes to coyotes,to deer.I shoot 100 gr Barnes-x and that works good,or the 115 gr Hornady.
If I had a choice of guns in the 25-06 I would choose the Winchester Classic Sporter LT.
Choice of scope would be the 2.5-10x40 mm Scheeles outfitter scope.
