Like alot of kids growing up in the 60's I had a daisy spittin' image, I was 6 at the time, and the next Christmas was a Crossman pump .22 cal air rifle. Similar to the Benjamin's at the time. But the 1st firearm and I'm 98% sure on this was a Winchester Model 55 22 cal. single shot. Interesting little 22, we called it a single shot automatic, as it would fire the round and would blow back the bolt cocking the gun for the next round and ejecting the spent case out a bottom port. My younger brother wanted to shoot it one day so I loaded it up and showed him the safety, on the tang, how to load it through the top of the receiver, push the safety forward and shoot. I was smiling as he shouldered it and took aim, at the shot his left hand came from holding the gun and he was shaking it vigorously. If you got your hand under the ejection port that spent 22 shell would fall into it and it was H-O-T! I had a good laugh, but, dont ask me how I knew that "could" happen.
