This was my question
Let me rephrase my question; out of all the guns sold in India each year how many do you think are chambered in the calibres you mentioned (7.62 Tokarev, 6.5mm Swedish...) and how many in the four calibres I mentioned?
A new firearms manufacture has launched a 30 cal tarkov (7.62×25) pistol in India, 30.06 cal rifle is being manufactured by IOF there are a significant number of 6.5×55mm swedish, 7x57 mauser, 375 H&H Magnum in rotation mostly they are pre 1980 imports. I have personally seen 3 7x57 mauser bolt action rifles and 2 375 H&H Magnum 1 break barrel (DB) and 1 bolt action at a friend's gun shop in a small town in UP.
