Several years back I read a story about the Pathan warriors of Afghanistan during their fight with the Russians. They were largely equipped with copies of Enfield bolt action rifles and very few factory rounds of ammo. They developed a cottage industry reloading the rifle brass to keep their warriors in the field killing Russians. For powder they had thousands of pounds of celluloid movie film that was cut into small flakes and made a very usable rifle powder. The spent primers (Berdan) were pried from the cases, a small punch was used to flatten the firing pin indent and a priming mixture was made up using match heads as the main ingredient. I don't recall if or what the story said about projectiles.
