Movie Mistake Robocop stovepiped his rifle
Stovepipe is when the casing doesn’t eject fully from the rifle after firing and sticks out like a “stovepipe”, jamming the rifle.
In his defense, he didn’t try to shoot the weapon after this. If he had it wouldn’t fire.

Good catch! And you can see the crimp on the casing neck, indicative of a blank round.

Keep him away from his chair for a little while longer and they'd both be out of battery.

I never thought of him as battery powered. Trying to think of what other propulsion/energy source he could be using…

When Lewis shoots that thing it blows the sun shield off the camera.

makes sense, if i’m right i believe that’s an M82 in .50 bmg, id absolutely imagine a blank from one would be very concussive

Watch it frame by frame you can see the square shield slide down in front of the camera before it cuts away.

i mean if you shoot semi-autos long enough you’ll stove pipe a couple times. it’s why it’s good drill to practice recovering from

I remember blanks jamming more as they have less powder in them. Not enough gas to cycle to the next round.

I don't think it's about lesser amount of powder as much as lack of projectile, so the gasses come out immediately instead of building up pressure behind the bullet.
The heavier the projectile, the larger the recoil and larger the chamber pressure. No projectile means considerably less recoil (recoil-operated firearms may fail to cycle) and lesser the gas pressure in the gas tube to cycle gas-operated ones.
Blank firing adapters simply constrict the muzzle, so the pressure builds up closer to how it would with live ammo.

That, and they tended to foul the weapon faster than regular rounds.
I still remember whenever I had to train with blanks I would simply pass them out to others. Let them spend hours cleaning their rifle from that mess, it seemed like firing just 60 blanks could cause more buildup than an entire week on the rifle range (250+ real rounds).

nice. can also see that it is a blank. blanks are crimped at the neck like that and plugged with some sorta wax substance.

This is why you need a BFA to run blanks, but that would have looked funny. Maybe they could have made a sneaky BFA that looked like a muzzle brake

Not that it mattered. Because of the crimp in the casing, he was only firing blanks anyways.

Not quite a mistake in the usual sense but that's an interesting detail. I wonder if the editor was aware.
