I found a bullet in the high desert of northeastern California, right near the Nevada line in Indian and Pioneer country. The bullet is just like a civil war three ring minie and weighs 470 grains. I would have guessed that it was shot in an 1873 Springfield, except that it has 8 groove rifling marks. The lands are roughly .050 inch and the groove roughly .150 inch. I guess there is a posiblility that it is not as old as I think, but it looks nearly as old as bullet dug up in civil war battlefields. Anybody have any ideas of what it may have be shot out of? I'm leaning towards some sort of trade rifle.
