Cliff , you are doing fine. Old eyes don't see as well as young eyes do. As I have stated several times on here , I USED to be able to make head shots on Squirrels with my Ruger Single-Six .22LR. That was a couple years ago or so... anyway now days I have a hard time telling which end of the Squirrel is the head.
If you are shooting at distance make sure to use a target you can see.
