History
Louis-Nicolas Flobert invented the first practical metallic cartridge in 1845 by inserting a projectile into a percussion cap — no separate powder charge, just the priming compound as the propellant. This became the Flobert cartridge, available in several bore sizes. The 9mm Flobert shotshell variant found a lasting niche in European garden guns — break-action rifles used for pest control in orchards and gardens, where minimal noise and range are virtues. RWS and other European makers still produce it. In the US it is rarely seen, but in France, Belgium, and Germany it remains available for traditional garden gun use.
