I think where some of those folks fall apart (whether regarding scope testing or smaller caliber useage) is they tend to contradict themselves and resort to arguments based on emotion rather than data.
As far as shot presentation: after a partial listen of the most recent JVB, he made that case. But nobody is out there forcing people to pull the trigger. I'm not accusing you of making this argument, but it does seem to creep up, and I just think it feels disingenuous. If you don't have a good shot, don't take it.
