I have a Hawkeye that I was able to write off as a business expense. I use it for a number of tasks and it has paid for itself. In addition, I really like the 90-degree eyepiece.
However, it is possible to know too much... I let a really nice Cooper 223 AI go as the bore looked ugly. As MD pointed out there is relatively little correlation between how it looks/shoots, and yes it shot great.
