I want a light weight hunting rifle that would be good for elk at 500 yards but could also be used for deer and antelope. I am considering a 6.5 PRC in the new Springfield arms 2020 carbon waypoint and the Fierce Carbon Rival. Both can be purchased for +/-$2300 I am also considering the Cooper 92 backcountry. I am 71 and my 300Wby accumark is fantastic shooting rifle but heavy for the hunt. Is anyone had experiences with these rifles?
