My Grandfather took me out to a farm and taught me how to handle and shoot a pellet rifle when I was 5 or 6. A year or two later we went back and he moved me up to a single shot 22 rifle.
After that I was on my own.
I spent countless hous and boxes of 22 ammo at Boy Scout Summer Camp at the rifle range. Just loved range time.
That is how I got started 50 or 51 years ago.
