there are several questions. maybe the biggest question is why and how there was a live round, one or more, on the set. but there s the entire chain of custody of the gun and how did it get loaded and how did it get to the first a.d. and went to the actor without the normal processes? it s really jarring to think that somehow a real round got onto a film set. it s number one on the firearms safety bulletin for motion pictures and television, is no live ammunition anywhere on a studio lot. under the extremely rare situation where someone would need to shoot live rounds for a scene, they would go to a shooting range and be under very carefully controlled circumstances. so is it something that migrated into a box of dummy rounds? somebody made them home made or made them of poor quality? were rounds mixed up on a range on a previous day and brought on to set?
