They broke the mold...

With all the fun of this, and this, and even this, one has to wonder where all those little .36 inch balls come from.

Well this little handy is a .36 caliber bullet mold. It's designed to make .36 caliber balls out of melted lead - one round at a time. Certainly not a mass production device, but probably adequate for passing time around the campfire. You could make a couple of dozen rounds in an evening, provided a source of lead, a hot fire, and a melting pot.

The sprue would have been cut off with a pocket knife or file.

Now...if only you could make black powder...you'd have just about everything you'd need.
