The 22 is a great way to start. I like targets with small dark bullseye with a light background, or vice versa. Stay at close range until you are confident that you are shooting as well as the gun can at 25 yards. When I was in the Boy Scouts the rifle merit badge required a group of ten shots scoring high on an nra smallbore target. My merit badge councilor allowed us to pass if we put 10 shots under a quarter at 25 yards. That takes some practice, but it is a good goal. When you reach that at 25, move to 50 and so on. Occasionally add a reactive target. Something that explodes or pops is fun. Be sure to clean up after yourself. And have fun.
You can't fix stupid....however ignorance can be cured through education!
