Old cartridge id

In a box lot from an estate auction I found a bullet with a woven paper like material as a case. The bullet dia. is .525 and lenght of .975 . total lenght of 1.75 . the ‘case’ is torn, ragged edges with no way of knowing its total lenght. There is no base/bottom to it.

Khege–Can you post a picture. Just a wild guess without more information, but it sounds like you MAY have the remains of a .52 Sharps Linen from the 1860’s.
