I like to think of myself as a great long range shot and I am…mostly. Yes we miss too. It is often the lack of practice or as some say perfect practice that gets us out of the x-ring. Fact is I can stand to go back to school on shooting technique, breathing, slowing my heart rate before the shot. I have found a great article for you and I to read and reread and you don’t have to fire real bullets!

There is enough here for free for you and I too learn. More later…
