Loose Cannon,
I got a Mattel Fanner 50 for my six birthday. It came with plastic shells, that you pushed plastic bullets into against a very heavy spring.
Then, you loaded the completed shells up in the six cylinders, and when you pulled the trigger, something in the mechanism freed the bullets and they few out of the barrel under the spring power. Greenie stick-em caps were to be stuck on the backs of the shells, so that the caps fired off as you shot.
Problem was, those little gray bullets flew out at all sorts of crazy angles, and when really far, and it was nearly impossible to find them. And, it was impossible for me, as a six year old, to push down hard enough on the bullets to reload them against the heavy springs. (They had a hole cut in the stag handle grip to help push the shell down onto the bullets, but I couldn't do it.)
So, I just gave up on the bullets, and used the stick-em caps.
All in all, though, it was a very poor design compared to the six shooters that used a roll of caps, and a real real disappointment. The T.V. commercials, which I am sure you saw, made them look absolutely terrific, and like you, I just HAD to have one.
