You are thinking of the term "Instinctive" or as you put it "Instincts" to literally.
Instinct combat shooting: The act of operating a weapon by focusing on the target and instinctively coordinating the hand and mind to cause the weapon to discharge at a time and point that ensures interception of the target with the projectile.
This is a skill that most definitely can be learned. If it is the term (everyone is using) that you are worried about then that is just semantics...
