DO NOT SELL IT. You will hate yourself later. I'm sure brass can be made from...something. Then you can shoot it. You can even use it as a deer rifle if you are hunting thick woods from a stand or jump shooting whitetails up close. It's not a real potent number, and was popular as a guards gun in prisons in the early 1900's.
You'll probably never NEED a gun. I hope you never do. But IF you do, you will need it worse than anything you've ever needed in your life.
IF we're not supposed to eat animals,
howcome God made 'em outta meat?
