This YouTube video title, "O menor cartucho que eu tenho: será que 4mm funciona mesmo?" (The smallest cartridge I have: does 4mm even work?), suggests an exploration and potential test of a very small caliber firearm or ammunition. The focus is on the functionality and effectiveness of the 4mm cartridge, likely involving a demonstration or range test to see if it performs as expected, despite its diminutive size. It appeals to firearm enthusiasts curious about unusual or less common ammunition types and their practical applications.

This video showcases the 4mm Swiss M20, presented as the smallest round in the collection. It's compared to common calibers like .22 LR, .308, and .50 BMG, highlighting its diminutive size. The 4mm M20 is noted to be primer-powered due to its small bullet, making it a unique sub-caliber training round.

The Le Petit Protector ring pistol, often mistaken for a 19th-century antique, is revealed to be a modern 20th-century production designed to mimic older French designs. This 5-shot, 5mm pinfire revolver lacks a barrel, resulting in extremely low velocity. Its internal spring mechanism is cleverly integrated into the ring band itself. Evidence suggests it's a modern replica due to English spelling, inconsistent cases, and its absence from key historical firearm texts.
