I may have told this story before... as a teenager I used to strap my dad's 1920's .22 single shot rifle across the handlebars of my bike, ride out to my friends house about 4 or 5 miles out and we would spend the day target shooting... or favorite targets were the brass off the .22's sitting on top of a fence post... I got pretty good at knocking them off the post.
Haven't fired a gun since 1964 when I commented to the second class gunnersmate that I had never fired a .45.... as a p.o. 2 myself was supposed to be qualified with a .45, so he took me to the fan tail of the ship where they had just launched a weather balloon, handed me a .45 and said "shoot the balloon, don't worry the .45 won't penetrate it.".... don't know if I hit the balloon or not, but pretty certain I hit the Pacific ocean.
