I use a fixed power 10x Bushell Elite 3200 ... it has a mil-dot reticule and easily adjustable turrets with either 80 or 100 MOA of total vertical travel ... I forget. It returns to zero reliably and I have been happy with it in just about every way. I figure that it is easier to make a quality fixed power scope for a given price than it is a variable power scope and 10X seems adequate to see well at just about any range from 40 to 1000+.
Never tried anything other than my spotting scope at higher mag, but that one sure sees the mirage (helpful to read the wind), so I'm inclined to believe the distinguished shooter in WY ... as though that were the only reason
