Ok, I'm thinking that this is some sort of lead weight but how old is it and what would it have been used for ? It was found down by a local river, pretty heavy.
I believe you are right it looks a free fishing weight.

Looks like a duck decoy weight. Could be pretty old.
Sorry but I just couldn't resist with all the comments about taking good photos of your artifacts.
We have a really nice colored background that works well for most photograph.
Then that nice background is covered with a the worst thing to use for a background - a white sheet of paper.
Then the artifact is held in the hand above both backgrounds taking it out of the plane of focus.
Now that's a lot of work to take a pic.
The only way to really understand something is to play with it.
Sorry for the bad background, that was actually used for other pics I had taken. I used my hand so that you all could get some idea of the size of the object. I'm not a professional photographer lol
None of us are. Can't you tell?
just like detecting, it takes practice lol
But after putting on my sunglasses to veiw your post
I still cant really tell what you might have there
