Old salvation army pin, 3 ring bullet and a few mysteries!

[diabolicalbeans]

Today I found a few interesting little things, the first being a salvation army junior soldier blood and fire pin (any clue how old it is?) Then around the same area as the 1700's shoe buckle I found this oval piece of metal that appears to be hand hammered (any clue what it is?) I then found this threaded ornate ring, I think it's brass but I'm not sure, perhaps it was part of a pocket watch or something? And lastly I found this three ring bullet (does anybody think that it's an old bullet, or perhaps a modern shotgun slug?)

Nice finds! I'm not an expert but I think that bullet might be a modern muzzle loader round?
