What it is

A family of smokeless propellants made by combining nitrocellulose and nitroglycerine with petroleum jelly, developed in Britain to replace black powder as a military firearm propellant.

Cordite shortages in the First World War led to the creation of the HM Factory at Gretna, which produced about 800 tons a week.

What it led to

  • Standard ammunition for the British .303 rifle from 1891
  • Use in artillery, tank and naval guns
