I would agree with most of your post. However, comparing shooting 3-4 inches at 30 yards at a stationary target is not even close to being the same as shooting at a living, breathing, moving moving animal at 30 yards. Comparing the two IMO is tuff to do. I would agree that your shot was a very good shot and you should pat yourself on the back for it. I wouldn't just brush it off as if it were nothing.
