I love to shoot; obviously why I have brass laying around. So I decided to use the head stamp of a bullet. I dug through my brass pile until I found a 38 Special with good markings and a silver primer.
1) Cut and remove the excess brass. I used a jar opener to prevent the pliers from digging in.
2) Grind the backside of the stamp until flush. This was the most challenging of the process. If I used pliers to hold the piece on the grinder it dug in and ruined the sides. I ended up just holding it by hand and going really slow so it didn't heat up.
