I find a fast moving snake to be a very difficult target.
One of the best ways to determine this is to compete. Try bullseye if you want set distance at stationary targets, bowling pins for accuracy and transitions while under time pressure or IDPA for defensive pistol/revolver shooting, movement of shooter and targets, time pressure, tactical instruction, etc. When you compete, you will see what “good” looks like and find out what good is in that particular discipline.
