When I was 12 I wanted to learn to shoot. My guardian said do your chores, milk the goats sythe some alfalfa daily for the animals and I will give you 22 ammo and a tiny 22 revolver with a one inch barrel. With a box of 50 rounds he nailed a sheet of paper and a playing card with the ace of spades in the center of it. He drew me a picture of what the sight pictire of the pistol should look like and said stand here. He said when I made 3 holes in the spade I will let you use my model 62 pump winchester to hunt rabbits for dinner. It took a awful lot of concentration and squinting but in two boxes of ammo I did it. And shot cottontails for dinner with the rifle from then on. At the age of 14 I was the youngest NRA junior Distinguished Expert in my State and at 17 I was on the State National Guard Rifle team and won the hat off of the Commanding General for helping a Guard Team beat a Marine team for the first time in California history. I have had a career as an officer, a reloading tool dealer a manufacturer and have had a very interesting life. It pays to concentrate.
