I'm not sure how this situation happened (I assume details aren't out yet anyway) but with Brandon Lee the issue was the gun had to appear loaded but also be able to fire a blank. The easiest thing to do is use a real gun and two different types of prop ammo (rounds with bullets but no powder or primer, and rounds with powder and primer but no bullets (blanks)). They could avoid this by having two types of prop guns, one that can appear loaded but has no firing pin, and one that has a firing pin but which can only chamber blanks. The situation that killed Brandon Lee was one in a million (or at least seemed to be previous to this) and the extra effort wouldn't be worth it especially because they incorrectly left the primer in the no powder or primer round.
They also need to check the barrel. In the case of Brandon Lee they knew the chamber had a blank round but they didn't know there was a bullet in the barrel.
How does Hollywood still not have a prop gun that cannot hold or fire actual projectiles?

They probably should stop making the rounds by hand and contract an ammunition company to make it for them.
But that'd be "funding the gun lobby" or something so they can't do that.
Really all the needs to happen is people not be fucking stupid and check the damn chamber before playing make believe.
