Bullet Powder Casting
« on: August 29, 2011, 07:14:30 PM »
Has anyone ever seen a powder casting like this before.  It's made of a material like the old
egg cartons and there appears to be gunpowder cast into the molds?

To control pressures in large artillery powder grains got very large and were pressed to shape rather than pressed into a cake and then broken. This allowed control of the grain size and slowed the pressure rise when using 100-200 pounds for a charge. Some powders were the size of small apples.
The 303 British service cartridge was originally loaded with a single cylinderical  pellet of BP pressed to the required shape when still damp.

W.W. Greener's "The Gun and it Developement" the 1896 edition shows a wood cut of powder granulations and one is a cylinder with a hole through it.

I'm wondering if the form were removed, would these by cylindrical.  I wonder if it is for the 303 you mention.  It looks too large for that caliber.  Maybe this guy
came up with his own loads for muzzleloaders?

That is very strange. How do you safely store one of those? Kind of looks like one of those match light charcoal blocks. BOY THAT WOULD BE A REAL WAKE UP CALL!!!

The guy sent it to me UPS.  I didn't realize it had powder in it when I ordered it.
Could have been interesting.
