Looking for the best hunting scope out there. I have a budget of $2000. Its goin on a .300 RUM. I mostly hunt in louisiana where most of the longest shots are 300 yds but there is a time or 2 that a 500 ud shot is possible. But once a year i go to nebraska where a 300 yd shot is regular and 400-500 shots qre quite possible. So what yall think fellas?!?
