Is this a period bullet?

[RustyRelic]

Found this today but it's not where any activity took place , not that I know of. I see two rings and it's pretty deformed. Just wanted to see if it's the real deal

A heeled rimfire bullet IMHO. How much does it weigh? Knowing weight could help determine caliber.

 

[RustyRelic]

I don't have a scale , that's something else I need to get. I guess measurements won't matter since it's been struck and misshaped

It looks kinda like it could be a pair of stacked bullets fired at the same time. A weight measurement might provide some insight.

Best I can do

Maybe @Tom Hughes will know.

I've never seen a CW period bullet like that before. Looks like an old patina, but then again it could be from a fired muzzle loader from 70 years ago.....

Thanks for your insight Tom

If that's a gas check, probably no.
