I made a ring out of the used casing from a 223 because I mean what else do you do with them? anyway this is a super easy way to put those empty casings to work. have fun!

Supplies

what you'll need:

empty 223 rounds(or mostly any rifle round)
a hammer
two pliers
some pretty strong glue

Step 1: Flatten Casing

take the hammer and-on some concrete or something- hammer the casings flat(except for the rim and head).

Step 2: Bend Shell

bend the casing so that they both fit over each other and are even, and so that it will fit one of your fingers

Step 3: Glue

glue the casings together so that it will fit the finger of your choice.

Step 4: (Optional) Customize

on one of my rings I glued some peridot on the ends just to add a little more "flavor".

Step 5: If You Dont Have Bullets... Print This

you can customize this to your ring size if you want to. thanks for the bullet design by glacey at thingiverse.
