Ballistics
Velocity only, no drag model: no published ballistic coefficient is on file for 6mm Flobert, so this is the shape gravity alone gives the advertised velocity. Drag would steepen it. The tool below solves real loads through their published G1 or G7 model.

Drawn at true 1:1 — every case is accurate relative to the others. Absolute size depends on your screen's pixel density, so measuring one against a real ruler may be off. 6mm Flobert is highlighted below.

History
Invented by Louis-Nicolas Flobert around 1845, the 6mm Flobert is one of the earliest self-contained metallic cartridges. It uses only the priming compound as propellant — no powder charge — giving it very low velocity suitable for indoor shooting galleries. It remains in production by European manufacturers including Dynamit Nobel and Fiocchi.
