Hey guys, y’all always pull through for me, testing my luck again. I found these two items this past weekend in SW Mississippi at an old homesite. Didn’t find any coins, but did find some turn of the century shotgun brass. The brass item appears to be either a handle or a guard off something. One end is broken, the other was made that way. The bullet appears to be a .58 cal, but with all the teeth marks it ranged from .56 to almost .59. It is 1.09” long. Were the grooves chewed through, or was it originally smooth? And what does that, a human or an animal? If human, was it like biting a stick for pain, or just something to gnaw on and pass the time? Thanks for looking.
