Every high school should have an air gun range and classes offered. Basic marksmanship is easily and economically learned with air guns.
I wholly agree with you. When I was a high school freshman (1950-51), were near Crosman Arms, who provided CO2 powered .22 cal pellet rifles, bullet traps, CO2 cartridges, and pellets to organize interschool rifle matches in the area. Our instructor and coach was an Army veteran, and we took time in our lunch hour/play time to practice.
That's where I started to learn to shoot, although I alrady had a BB gun. Later on, I was on the Syracuse University Rifle team; and received Army Expert rating in M1 Carbine, M1 Rifle, and BAR (plus Master Gunner 81mm Mortar).
In 1995 I shot in a DCM competition shoot, and (after 30 years) came in 3rd among regular shooters with the M1 Garand rifle. I still regularly shoot at age 75, as well as I did at 25.
With this score, and $265, I got my own M1, which I still have.
