Ok, I can see how blanks are called live rounds. Still my understanding is: 1. The person handing off said 'cold gun' which to me implies the weapon was not charged with anything. Please clarify if I misunderstood. 2. The victim was shot at a distance. This makes it probable there was an actual bullet in the weapon. Why assume anything different? So I still wonder why there would be bullets around on the set.
