I haven’t been very succesfull with my last call to shotshells collectors.
It was : “If you have a scarce shotshell caliber in your collection, please tell me which one”.
So let’s try in another way !
Here above is a first listing of all the different shotshells calibers I know.
If you know some others you are welcome to drop me a note.
No variations, only calibers.
No mortar propeller or engine starter
I will put another listing soon with more primitive shells
