When I was about 10, my mother gave me her target rifle (she was on the high school team). It was a beautiful High Wall Winchester with a bull barrel, Lyman globe front sight, BSA vernier tang rear sight, and a custom hand-checkered stock. I was then enrolled in a NRA four-position, small-bore rifle course. I really learned the skills of marksmanship and gun safety through that wonderful experience. That was 50 years ago! Although I love shooting handguns and shotguns, accurate rifles have peaked my interest the most ever since.
About the same time, I received my first bb gun and roamed the woods a lot with it. I was the first in the neighborhood to have a break-open pellet rifle - what a squirrel killer that thing was. When I move to Missouri at 12, I was then able to roam the local woods with with a shotgun and .22 hunting rabbits, squirrels, and groundhogs. This was all done with buddies my own age as neither of my parents were shooters as adults.
Also important in my development as a shooter was my grandfather who died when I was about five. He left behind gobs of books, gun parts, shooting trophies, and a decade's worth of American Rifleman magazines. My parents sold all of his guns, though, when I was too young to effectively protest. My step-grandfather worked at Springfield Armory and tested guns for a living. He did not enjoy recreational shooting, but he did contribute to my knowledge of firearms. When he died, I obtained his books and manuals including original manuals on the 1911 (printed in 1917) and other guns of the era. I also have a manual on how to set the timing on airplane mounted machine guns so the bullets don't shoot the propellers off (the bullets actually were mounted behind the propellor and shot between the blades as they rotated).
I still love shooting and have my own backyard range. I don't shoot lots of ammo, but shoot several times a week. I was just practicing IDPA shooting this morning with my 1911.
