I was wondering if this is a .45 Whitworth bullet?

I found these on same farm that I found Confederate bullets and artifacts. I was surprised to find .45 caliber bullets this old and big. The only thing I came up with is .45 whitworth. Any ideas?
Thanks

It is possible. Check the base. What does it look like?

If your base look like this? $250-$300

A lot of them have that hexagon shape.

I found this one but it not a Whitworth

Nope I’m guessing something else.
