Ballistics
Velocity only, no drag model: no published ballistic coefficient is on file for 5mm Bergmann, 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.

Size vs familiar rounds
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. 5mm Bergmann is highlighted below.
