Kind of difficult to make out clearly but it actually looks more like a fired mushroomed bullet to me

Agree with Tokens

Mushroomed bullet

 

[Detector mom]

Makes sense. I find bullets galore at this spot, usually late 1800s/early 1900s cheap copper rifle cartridges. What type/date would this one be?

 

[tokens70]

Can't be sure on a year but appears to be around .30 cal. If it is copper jacketed, it won't be earlier than the late 1800's at best.
