My first gun was also a Red Ryder BB gun. I think the first "real gun" I had was .410

As for shooting wise, I honestly don't remember what the first non-BB gun i shot but i do recall a time when i was about 5, doving hunting my dad. We were with a bunch of friends at the time and it was later in the season so it was pretty slow. Either i or my dad asked me if I wanted to shoot his gun, which was a 12. Browning Semi (which now is almost as old as i am). There was a soda can near by and my dad helped me shoot it but when i did, naturally everyone with hearing distance turned around in a hurry lol. I also have a similar story to TBs of slaying toads. During the summer time i would go out in the backyard at night armed with my BB gun and a flash light and shoot cockroaches lol.

For my next shotgun (I still have my dad's old shotgun as well as a remington 870) I would like to get an Over/Under.
