Gunr, A Big Welcome to You to the Tnet forum from Georgia. The bullet you have at a glance looks like a 3 finger Minnie' ball from our Civil War. Gently try to clean out the hole in the bullets end. If you see what appears to be threads like a screw, it has been pulled. You probably already know this, but soldiers carried a small tool in their cartridge box called a "bullet worm". This was a small iron piece that would be affixed to the end of their ram rod. The work had a twist pattern and a pointed end. The soldier would ram the point of the bullet worm into the top of the soft lead of a bullet and twist the work into the soft allowing the bullet to be pulled from the muskets barrel. This was used when a bullet would not fire or discharge from a soldiers musket. If this is what your bullet is, that is a nice save.
