Once rifle season starts they may not stand around a waterhole in broad daylight,if you are looking for an easy gauranteed kill antelope may not be your best bet.Once the shooting starts you had best be prepared to take that 300 yard shot,lopes wise up real quick.I watched a archery lope huntin WY on Outdoor net yesterday,guy sat in his blind for 6 days before getting a shot.Id spend the extra money and increase your odds of taking a buck,I dont know about WY but you would have to draw a tag here in MT.
