My first firearm was a Stevens single shot, lever action, rolling block .22. A few years later,I got a brand new Remington .22, so I sawed the barrel and stock off the old Stevens and made it into a pistol.
The new rifle was also single shot, but heavy barreled and highly accurate. It was the Model 513T Matchmaster and came with peep sights. I did head shots on snapping turtles in our pond.
