While I never used any of the old Pakistani .303 ammo, I did ask the Indian Army Liaison Officer what the Pakistan Ord Factory used as propellant. He assured me that it was most definately curry powder. All here - and no there! He also told me about the problems that the PkAF had landing their newly purchased MiG fighter aircraft. The Chinese didn't teach them how to land them. They simply told the air crews that the Indian Air Force would ensure that they came down - eventually!
