Picked this up from a friend. Total is 36 lbs. The clear plastic tubes have several cast bullets in them, caked with a dry flaky wax. They are murder to get out of the tubes, so I cut one open to check them out. They appear to be black powder slugs for storage & carrying purposes.
Additionally, there are musket style balls in there, plus a couple varieties of projectiles - some round nose hollow base, round nose solid base, solid base conical, etc. There were a handful of really large projectiles he said were BMG bullets but I've never seen one up close myself.
I even got a primer pocket cleaner bit in the mix.
