Ball Bullet ID , odd caliber

[Goldstar1]

Can anyone help ID this caliber it appears to be a black powder ball round , but I can find anything quite close to these dimensions, it measures .429-.433 " and 120.36 grains if the scale is correct. Any Idea on the caliber or what would have fired this ?
This site probably saw its earliest firearms in the mid to late 1800s

Might be the ball ammo for a .44-caliber muzzleloading Single-Shot Pistol. There were still some of those around in the mid-1800s.

For anybody here who doesn't already know:
Muzzleloader bullets are slightly smaller than the gun's caliber (bore-diameter), and breechloader/cylinder-loading bullets are slightly larger than the gun's caliber (bore-diameter).
Examples:
Muzzleloading Springfield .58 Rifle bullet is typically about .570-inch in diameter.
Breechloading Sharps .52 Carbine bullet is typically about .535-inch in diameter.
Cylinder-loading Colt .44 Revolver bullet is typically about .460-inch in diameter.

Muzzleloading pistol or rifle, no way to really say which as both were made in similar calibers. Could be any age as well, I have a .433 mold for a rifle made in the 1970's.

Or from a .44 cal rifle.
