My dad had a .22 bolt action - a Winchester, we think (he's 87 and his memory isn't great). He took me and my brother out a couple times to shoot targets - I may have been around 9 or 10? All the memories are pretty vague, being so long ago. Didn't shoot another gun again until this year. So, close to 50 year gap. And now I hit the range every week.
My first was a Stevens .22 bolt action. Got it about age 8. No clue what happened to it. Next was a Stevens 12 gauge shotgun. Had it until after high school.
