This is my first instructable so i hope you like it. I was trying to make the necklace similar to the H.O.G (Hunters Of Gunmen) necklace which is given to USMC snipers when they graduate sniper school.
Step 1: Step # 1
Here are the things you need
Bullet shell (you can use any kind)
BB gun (if you don't have one any thing to dent the shell works)
Step 2: Step # 2
first you have to make a dent with the bb gun it makes it easier to drill through the shell. Then you drill through the dented part of the shell.
Step 3: Step # 3
measure the string around your neck and cut to the size you want and then burn the ends of the string.
Step 4: Step # 4
take the string and put it through the hole in the shell. and then you tie the string.
