I shot my first .22 when I was around 6 or 7, but not hunting. It was a very early production Win Low Wall single shot chambered for the .22 Long. My Grandson has this rifle now. My Grandfather bought it during the depression for less than a Dollar. I got my own bolt action single shot .22 LR at about age 11 & managed to kill a few squirrels with it, though I never shot it very well. Shot my first shotgun at around age 13 I believe, this would have been about '51. That one was a small frame H&R 28 gauge single, killed two rabbits with it that day.
The next year I began doing a bit more hunting, mostly rabbit, with a borrowed Stevens 94 20 ga single.
In the fall of 1954 when I was 16 I bought my first very own double shotgun, a J Stevens Arms & Tool Co 12 ga & began hunting more intensely. My Dad had hunted a bit as a boy growing up on a small farm but had not kept it up so I sort of started on my own. Shortly after this though he bought some Beagle Hounds & started rabbit hunting with me. As long as he was able I spent a fair amount of time with him & those hounds chasing the Bunnies around, but mixed in any other type of hunting I had opportunity for. Dad never cared for anything other than running those dogs. He didn't even care if he actually shot any or not, so I did most of the actual shooting.
