Isn't this how Brandon Lee got killed?
They'd used a gun to fire live ammo, didn't know that last round hadn't cleared the barrel. Later they loaded it with blanks to shoot at Lee during a scene in The Crow movie.
Blank round + bullet in barrel = bullet going downrange

I believe all movie firearms are modified to only chamber blanks. (MP5s firing 8mm blanks, or something like that.)
IIRC, The previous blank cartridge broke, leaving part of the case in the barrel. The next blank cartridge came along and happily propelled this improvised bullet into Lee.
ANd according to Wiki, I would be wrong:
"Because the movie's second unit team was running behind schedule, it was decided that expedient dummy cartridges (cartridges that outwardly appear to be functional, but contain no gunpowder or primer) would be made from
real cartridges by pulling out the bullet, dumping out the gunpowder and reinserting the bullet. However, the team neglected to consider that
the primer was still live and, if fired, could still produce enough force to push the bullet off the end of the cartridge. At some point prior to the fatal scene, the live primer on one of the constructed dummy rounds was discharged by persons unknown while in the pistol's chamber. It caused a squib load, in which the primer provided just enough force to push the bullet out of the cartridge and into the barrel of the revolver, where it became stuck.
The malfunction went unnoticed by the crew, and the same gun was used again later to shoot the death scene, having been re-loaded with low-power black powder blanks. However, the squib load was still lodged in the barrel, and was propelled by the blank cartridge's explosion out of the barrel and into Lee's body. Although the bullet was traveling much more slowly than a normally fired bullet would be, the bullet's large size and the point-blank firing distance made it powerful enough to fatally wound Lee."
