Hello, I have found various rimfire cartridges metal detecting. I am familiar with the standard 22 LR but not so much with any of the other ones I have found.
As a key for. Reference each square is 5mm, and number 3 in the photo is a standard .22.
I know the calibers of each shell as I have measured but I was just wondering if there is anything special about any of them as well as the proper and common names these cartridges are called.
They are all rimfire.
All information or ID is much appreciated, cheers Hamish.
