Ivobg sent me a Private Message, asking for my opinion. My answer:
Although you can fit a 5.5mm gun shell into it, I believe it is not from a gun, for two reasons:
1- The part of a gun which the shell/cartridge fits into is made of steel, and the object in the photo does not look like steel.
2- The part of a gun which holds the shell/cartridge must have a way for the gun's firing-pin to hit the cartridge's base, and the object in the photo is not the correct shape for a firing-pin to hit a cartidge's base.

Your TreasureNet Profile says you live in Bulgaria. Your writing of English language looks just as good as many Americans write in English.

You write in English much better than I can write the Bulgarian/Cyrillic language.
