I once bought a box of Indian military .303 surplus. 2 out of 20 fired. Has firearms/ammo quality improved there?
Reading an Indian gun forum, the answer is no.
Without competition, the guns appear to be merel adequate; people did not seem to find it remarkable to have ammunition failures of one in ten or so.
I looked at the official catalog for state arms.
They listed a shelf life of shotgun ammunition of five years!
They listed a shelf life of .22 ammunition of 18 years!
Maybe it is just a cultural disconnect, but I expect ammunition shelf life to be about a human life span.
