Thanks for the photo Fede.
To add a bit of background to some of the more obscure calibres shown. Here in the UK we have a list of “obsolete calibre” firearms which can be owned without license. This is on the condition that they are not to be fired and owned as collector pieces only. This law does not apply to ammunition in these calibres. In the last few years, criminal operations like the one in the news article have been set up to load these calibres for illegal use. The 11mm Mle. 1873 and .44 S&W Russian are common examples.
This list does not include calibres which are still widely made today, such as the .45 ACP, 9mm Luger, .380 ACP or 7.62x39 shown.
