A homemade cartridge with a conventional bullet replaced with a glue projectile.

https://en.wikipedia.org/wiki/Brandon_Lee#Death

In a film shoot prior to the fatal scene, the gun that was used as a prop (a real revolver) was loaded with improperly made dummy rounds, improvised from live cartridges that had the powder charges removed by the special effects crew, so in close-ups the revolver would show normal-looking ammunition. However, the crew neglected to remove the primers from the cartridges, and at some point before the fatal event, one of the rounds had been fired. Although there were no powder charges, the energy from the ignited primer was enough to separate the bullet from the casing and push it part-way into the gun barrel, where it got stuck—a dangerous condition known as a squib load.

During the fatal scene, which called for the revolver to be fired at Lee from a distance of 3.6–4.5 meters (12–15 ft), the dummy cartridges were replaced with blank rounds, which contained a powder charge and the primer, but no solid bullet, allowing the gun to be fired with sound and flash effects without the risk of an actual projectile. However, the gun was not properly checked and cleared before the blank was fired, and the dummy bullet previously lodged in the barrel was then propelled forward by the blank's propellant and shot out the muzzle with almost the same force as if the round were live, striking Lee in the abdomen.[101][102]

So two blanks, one with no powder and the other with no bullet, effectively formed one round of live ammunition. What a truly wild story.

It says they meant to point it upward and it slipped but "not drawing a gun in a crowd" would have been better.

Gun safety rules.

1. ALWAYS keep the gun pointed in a safe direction;
2. ALWAYS keep your finger off the trigger until ready to shoot
3. ALWAYS keep the gun unloaded until ready to use.

Every gun is considered loaded until proven otherwise. Every pull of the trigger will cost $10,000, as lawyers become involved, per NRA literature. Hearing damage by firing close to people is another risk.

I miss being able to watch Farscape the first time.

The guy at least had the foresight not to stick a real bullet in there

The next one might not because America's gun laws -- especially in Texas -- are based on voluntarily following good practises.

Whenever something like this happens, pro-gun people flock to the comments to pat themselves on the back by telling everyone that they would never do that with a gun because they have trigger discipline and they treat guns with respect.

But so what? They might never drive drunk but that doesn't mean we can abolish DUI laws.

What laws did this guy break and what is his punishment? Was it illegal to make his own sketchy blanks? Was it illegal to injure an innocent person with a firearm? Was it illegal to have a firearm at a wedding or to brandish it? Is he going to be prevented from owning firearms in the future now that he has proven to be a dumb fuck?

And most importantly, what is the pro-gun community going to do to prevent things like this happening again?

But we know the answer. He probably broke zero laws and will still be able to own all the guns he wants and take them to all the weddings he wants. His punishment will be minor or non-existent. The pro-gun community will do absolutely nothing to address the shortcomings of their laws, they'll just tut about it on the internet.

Republicans value $16 million a year and a voting bloc that will tolerate anything over people's lives. The gun lobby values profits over people's lives.

But the pro-gun community sells people out for convenience.
