Haven't heard of too many missouri river breaks on the east side. So you are on the west side. If you are bowhunting you better get online and purchse your tag now as NR tags went on sale March 1 i believe. As far as a rifle tag it will take at least 5 years to draw a NR muley tag. As far as animals i would think the biggest would be 160" deer some bigger but if you found one that big you would be doing pretty good. Depending upon exactly where you are at the response to NR hunters varies greatly, some areas they welcome you and some areas you are despised like you brought in the plague. Good luck
