These are not live rounds! And firing cap/ Primer end has been drilled out making it useless for any other purpose than key ring or display piece. These are made with REAL once fired shell casings and reload real bullets projectile. I actually drill the casing and install a clevis pin, these will not ever come apart unless you destroy the case to get it apart. I have many different calibers available make sure you select what you want. Or message me about a caliber if its not listed. I can only list a few pictures but glad to email or message you a picture of a specific caliber if interested. I do custom request if you send me your bullet or casing I can convert into a keyring. I am always adding new items so check back often to see what's new, I have added over 15 new rounds in last few weeks.
