By the way, dummy rounds come in different types. Some have a hole in the side. Some don’t have primers, or have a rubber plug where the primer goes (to give the hammer something to hit) Some look exactly like real rounds.
What is being described here are 4 rounds with holes in the side (which can’t be identified when the round is in the cylinder, they must be removed to see the hole,) and one round without a primer.
I know the Brandon Lee incident involved a dummy round where the primer was left on it. It got propelled into the barrel when shooting that scene. Then the gun was filled with blanks and the barrel wasn’t checked, causing the firing of a blank in the next scene to fire the dummy round out of the gun.
Is it possible the deadly round in this case was intended to be a dummy round, but was improperly made or prepared?
Assuming that the gun was used recreationally with real rounds by a random crew member in between scenes, and they left one real round in the weapon, how easy (or hard) is it for the armorer to make the mistake of filling the other 5 chambers with dummies but neglecting to take out the one live round? Assuming that she walks up to the gun with the assumption that it’s empty.
Of course, I understand that’s why it was said to lay out your 6 rounds on the table beforehand. If you’re pulling them out of a box, it’s certainly easier to forget how many you just put in.
