What is this???

Was hunting with a buddy a few days ago, and we dug this "thing" about 8" deep! It's very heavy, for it's size, and there's a "2" stamped in it. The quarter in the photo is for sizing comparison.  Was using an Ace 250 and I believe it was coming up on the screen as .10 dime, .25 quarter, .50 half, jumping between them. Can someone help us identify this? Thanks in advance.

Two ounce weight?

fishing sinker... made of lead... the number indicates its weight, usually in ounces!

    I think it looks like a 2oz weight like those used on toss nets.
