ya that looks kinda weird, perhaps I should explain.
I have a .54 caliber black powder carbine and make the bullet cartridges out of paper. I first soak the paper in a solution of potassium nitrate (spectracide stump remover works great). Then let dry before I form the cartridge for bullet I cast. The entire process is somewhat time consuming but very relaxing.
The quick and dirty way is to seat a bullet in the rifle by hand and dump 80 grains of powder straight in the chamber.
They look similar to these except the bullet I cast is pure lead and based off the Confederate Richmond Laboratories .54 conical bullet.
You want to put the fear of god into an intruder point a double barreled 20 gauge HOWDAH at'em. Carry two, they're small enough!
