What it is

A metal case that brought together bullet, powder and primer in a sealed unit which also sealed the chamber on firing (obturation). It made breech-loading and repeating firearms practical.

A collective Franco-British-American development: Lefaucheux, Flobert, Houllier, Pottet, Schneider in Paris; Berdan (United States) and Boxer (United Kingdom) fixed the centrefire primer design in 1866.

What it led to

  • Repeating firearms (the Spencer, the Henry, the Winchester)
  • Mass-produced ammunition and industrial military logistics
  • Machine guns
  • Hunting and sport shooting with commercial cartridges
