Indian soldiers oppose the use of Royal Enfield rifles/ guns because the cartage is made up of cow fats and pictures, Indian soldiers oppose the Royal Enfield weapon. And before inserting it, a sepoy had to pause for a while. Hindus and Muslims in the region were both outraged by this.

Rumours that the oil on these cartridges supposed to keep them dry contained pork or cattle fat (pork being repugnant to Muslims, cows being sacred to Hindus), thus their refusal to eat them, were one of the stated causes of the Indian Rebellion of 1857.

Bullets for muzzleloading rifles provided to native soldiers in India were greased with beef tallow in some cases, and lard (pig fat) in others. Pigs (and pig fat) were considered unclean by the Muslim warriors, and their faith forbade them from eating them.

The Enfield Rifle was instrumental in putting down the 1857 insurrection. Much more than most British historians since 1947 or the British officers of the moment want people to know. This propensity is reasonable because it undermines the post-1857 sociopolitical scenario's carefully nurtured idea of "White Man's Superiority."
