Actually, I've seen a few civil war musket/rifle ramrods twisted into approximately that shape. But in the long-distance photo you posted, I cannot see any characteristics to identify the item as a ramrod ...except of course for being a long thin rod of iron.
As you probably already know, a ramrod has a wide flat disc (or a wide cone) at one end (to push the bullet/musketball down the gunbarrel), and a short threaded section at the other end (for attaching a bulletworm, etc). If your item is a ramrod, the wide disc/cone part is broken off. But it should still have its short threaded portion at the other end. If there's no sign of such threading on either end of your item, it is not a ramrod.
