Could or could not.
“Depending on the manufacturing process, some have a hole in the casing. High-end dummies don’t, according to Carpenter.”
I can see it for rounds that might end up on camera, but otherwise? I guess the bottom line is to adhere to firearm safety rules. If that happens, even a negligent discharge shouldn’t kill someone.
I have armorer certifications from 4 different major firearm manufactures.
Dummy rounds were used in function testing of the firearms in all the courses. They were all clearly marked care being taken to make sure one could not mistake them for real rounds.
When training required the use of dummy rounds they were all clearing marked.
Now brightly colored plastic ones are used a lot.
I have a couple of striper clips that full of dummy training training for the 1903 Springfield dated 1918.
Even back then they new the danger of mixing live an and dummy rounds.

125gr vs 158gr.
Full case of powder vs half a case of powder.
Yes very common as many different powders have very different weights for their charges.
The so called industry expert if he allowed dummy ammo that could not be easily recognized from live ammunition on the set.
Is not an expert at all.
