Shot brass from a bullet maybe?

[North AL]

Can someone please help with this? I found what i believe is a shot brass from ammo. Problem is that it doesn't have any markings on it or at least they've worn off. Looks smaller than a 410 shell, but not sure. Wish I could've gotten better pics, but there's only so much that you can do with a phone! Also need help identifying this ring. Toy maybe? Has inscription on inside but can't make it out. Thanks!!!
