Based on the testimony given during the trial there was no shooting of live rounds anywhere on the "Rust" set. This rumor got started because prior to the start of "Rust" two other movies were being shot in Texas, "1883" and The Old Ones", Hannah was the Armorer on "The Old Ones." The producer of "1883" owned a large ranch where the movie was being shot, he wanted to let some of his actors get the feel of what it was like to actually fire the real weapons that were being used in the movie. He had a range set up on another part of his ranch away from the movie set where this training and shooting would take place. He hired Seth Kenny of PDQ props and Firearms along with Thell Reed (Hannah's step-father) who is considered to be one of the best movie armorers and firearms trainers to conduct this training and live fire event. They acquired the ammunition from Jay Swenson who provides dummy ammo for movies along with live ammo for other uses. He send down an assortment of ammo, various calibers and configurations. He provided three different 45 LC loads.
After this training and shooting was completed the extra live ammo was placed in a ammo box and plastic tote box and taken back to PDQ Props where it was stored in a bathroom away from all his other dummy and blank ammunition. PDQ provided weapons, blanks, dummies and other items to all three movie sets.
There was never any mention of whether Hannah was present at this shooting event. After completing the filming of "The Old Ones" all the weapons, dummy ammo, leather gear, blanks, etc. that had been rented from PDQ props was returned to them. Mixed in with this stuff was a box containing leather gear that belonged to Hannah which included a couple of holster that had dummy rounds in some of the loops. This leather gear was later used on "Rust."
The shooting on "Rust" happened on Oct 21 2021. The props van where the gun safe was was not searched until Oct. 27. PDQ Props was not searched until late Nov. five weeks after the shooting. The FBI analyzed the live ammo from PDQ (1883) and the other five live rounds found on the "Rust" set. The 1883 ammo was loaded with Trailboss powder the five rounds from "Rust" had a different flake powder like Unique, they didn't determine just what powder, only that it wasn't Trailboss.
The only 45 LC live ammo taken from PDQ during the search was loaded with a semi-wadcutter bullet and the ammo from "Rust" had round nose bullets similar to the dummy rounds. I guess we are to assume that the other two style of 45 LC at the 1883 shoot were used up and none were brought back to PDQ.
After the shooting the Prop Master Sara Zachary, who was a PDQ employee, unloaded two other Colt style revolvers and threw the ammo into the trash, not two boxes of ammo. She had only about ten minutes of training by Seth Kenny on how to load and unload a single-action revolver.
No other locations were ever searched to try and find where those six rounds on the "Rust" set came from.
Hannah used a very disorganized Rubbermaid cart to transport weapons and ammo. This cart was frequently left unattended with weapons, blanks, dummy rounds and leather gear on it. The prop truck had a safe in it for the weapons but blanks and dummies were not all stored in the safe. The prop truck was left open during the day during filming.
This whole set was a disaster waiting to happen. It was never determined just where the live rounds came from. Anybody could have dropped them on the cart, placed them in the prop truck or loaded them in the loops on a holster of bandolier.
Hannah should have check the dummies better, she should have only worked as an armorer, not assisted props. There should have been better training for everybody.
There is a lot of blame to go around.
I watch the trial from beginning to end and learned a lot.
It was almost painful listening to the "Experts" explaining the operation of a single-action revolver, how to load and un-load it, how to check if it is empty, how to convert a live round to a dummy and vice versa to the jurors.
One think that came out of the FBI testing of the revolver used by Baldwin was that it was in excellent condition and could not have fired unless the trigger was pulled. It could not have fired unless the trigger was pulled with a fully cocked hammer.
