Some people just don't shoot well or perhaps don't shoot well under the pressure of a high priced hunt. I suspect many over think things and that riles them up, shakes, blurred vision, etc.

Just because a person can afford a hunt, doesn't mean they actually shoot the rifle they are bringing, or any rifles for that matter.

My buddy Keith, still in excellent shape and guiding at 75yrs old, has one of the 2 or 3 leg trigger sticks for his hunters. He said now they hit where they are supposed to.
