There was a science teacher named Towers, who was a tinkerer that figured out how to separate the anvil from used primers, flatten the primer face and add a very small amount of Mercury Fulminate to make a working but sensitive primer. He was kind enough to pass on both the knowledge as well as the MF to me.

Black powder was easy to find and cheap.

So...I started reloading with a block of wood as a shellholder, a nail filed to fit the primer as a deprimer, a wooden dowel to seat the wad and another larger one to press the crimp down, different sized pipe to cut wads and size cases. and a mallet instead of a press.

I loaded hundreds of .410's with that rig...and had a few accidents loading primers
