I was sawing up some American Cherry yesterday.
as I opened up the bookmatch, I found two shiny blobs, one on each side......

what on earth?
clearly not iron or steel as the saw never made a sound as it went through......
so hoked them out of the wood...

and it's a bullet!!
the next couple of slices have a hole where it passed through, then the next (on the right) has a split. other cuts after that had noting.... no mark at all.....

so I'm thinking this has been in there a LOOOOOONG time....
I've seen barbed wire and nails and rubbish before, but NEVER a bullet!!
I've heard of guitars being shot, but never before they've even been built!
