Turner Kirkland the Dixie Gunworks founder found a device used to flatten hair and saw the potential to make a mould from it.
By using a "cherry" to ream the cavity to desired shape he had an economical device.
They did sell them solid at one time so anyone could cut what they wanted for a shape. Not sure if they still do.
Dixie Gun Works muzzleloading, blackpowder and rare antique gun supplies.
A cut one for .36 cal runs 55 dollars today, or last listing seen anyway..used sell fifty bucks, less for roundball moulds or whatever a buyer will pay. I don't see them still listed. Blackpowder shooters might be the best customers for resale.
You have one Keth style bullet.(Elmer Kieth was a .44 mag promoter and his style bullet has multiple uses. Even in a .38 ,even seated backwards sometimes.Though a 158 grain hard cast Kieth style with a gas check loaded as designed is about tops....
Your bigger bullet is like a Lyman style. Solid or hollow base probably an option as with a hollow point or not.
The grooves are for holding lube.
