Gee, wonder where those bullets go. Outer space, right? :/

Outer space, right? :/ Everything I've heard is that celebratory gunfire isn't dangerous if it's fired straight up. A bullet falling straight down can't reach a terminal velocity to be lethal.
The story is that cases of fatalities are due to shots fired at an angle. Gravity pulls the bullet to the ground while it still has sufficient forward energy to be lethal (traveling forward faster than it would if falling straight down due to gravity).
We had a local girl hit in the side of the head and killed. It was attributed to celebratory gun fire (when it was probably someone shooting at a traffic sign at a 30-degree angle 3 miles away).
A kid was hit in his bed. The news called it celebratory gunfire. Then proceeded to show the bullet hole in the side of the house.
I'm not trying to justify celebratory gunfire. It's reckless and eventually leads to someone discharging a weapon at an angle (instead of straight up). But, I think it gets a worse rap than it deserves. The problems are caused by people shooting at an angle, and victims hit by forward-moving bullets. Not falling bullets.

1 edit | People who think (or don't think) like you get people killed. An excerpt from wikipedia on the terminal velocity of a 150gr bullet falling back after being fired straight up:
In this case, the terminal velocity increases to about 320 km/h (200 mph or 90 m/s),[2] which is also the terminal velocity of the peregrine falcon diving down on its prey.[3] And the same terminal velocity is reached for a typical 150 grain bullet travelling in the downward vertical direction — when it is returning to earth having been fired upwards,
Let me hit you in the head with a 9mm 147gr JHP traveling at 293 ft/sec and you let me know how it feels. Your post is sheer idiocy.

150g at 200mph is the equivlant of 1.7j of energy. 1j of energy is a tennis ball at 14mph. So, sure, I'll take a hit. It may leave a tiny bruise, but it sure won't kill you.

A quote from the link above:
Mohler also told them about a case of an elderly man in Alameda who was talking to his wife underneath a plastic corrugated roof in his carport. His eyes rolled up and his wife thought he was having a stroke. When they got to the hospital they found out there was a bullet in his brain and, unfortunately, he died.
"I know for a fact that bullets fired at a distance, returning to Earth, with terminal velocity, have the ability to kill people." - Dr. Mohler
____________________________________________________
That bullet went through the corrugated plastic roofing material, into the man's head and killed him, at terminal velocity.

Thanks. That hurt my brain. They went through a lot of convoluted tests before finally getting to the real test: just drop slugs from height.
There's no need to determine how high they travel. (All that matters is the distance it takes for them to reach terminal velocity, how fast that velocity is, and the destructive energy of something with that mass traveling at that velocity.)
Just drop 'em from that height (about 500'?). Which results in the destruction of a BB gun fired at 2-3' distance. It could break the skin.
The thing that always irritates me about news reports of celebratory gun fire is how they show incidents of rounds entering at a lateral angle. Some idiot shot at a bird or sign. That's a lot different (and dangerous) than firing straight up.
But, firing straight up is stupid. I just think it's weird the way cities pass special laws concerning celebratory gunfire when it's already covered under "illegally discharging a firearm within city limits."

This is what bothers me about the panic over "celebratory gunfire." Nowhere in that article did it say the bullet passed through the roofing, nor the angle of entry.
In Phoenix, we hear about incidents like this, but then it turns out the bullet came in at a 30- to 45-degree angle. Most people don't consider shooting at a bird or sign within city limits to be celebratory. That's clearly a dangerous act. (A bullet traveling at 600fps or greater.). Not as dangerous as a bullet falling at 200fps.

I don't know how you arrived at your figures. However Rex Magnum powder loaded 6 grains behind a 9mm 147 grain bullet yields 387 ft/lbs of force @ 1091 ft/sec. If you lower that bullets speed down to 293 ft/sec (200mph) it is still generating approximately 104 ft/lbs of force on an area that is less than 3/8" in diameter. Be my guest step in front of it.

Let me do the math for you. I'm using the worst case scenario.
A 9mm bullet weighs about 8g.
Terminal Velocity as tested is about 150ft/sec.
Using the formula to calculate joules (kg*m/s^2), you come out with appx 6.9 joules of energy.
If you drop a small apple from 25', that is the same amount of force of about 7 joules. Trust me, it WON'T KILL YOU. As stated before, worst case scenario is it breaks the skin.
The only WAY it could kill you is if the HORIZONTAL velocity (i.e. fired at an angle) is still high. A bullet traveling at 600fps is NOT a linear power increase, it's a logarithmic increase. 600fps would result in over 125j of energy, which could certainly kill you.

said by GadgetsRme:lower that bullets speed down to 293 ft/sec (200mph) it is still generating approximately 104 ft/lbs of force on an area that is less than 3/8" in diameter. It sounds like you're emphasizing the bullet's mass. I agree with that. If it's a pointy, full-metal-jacket (non-deformed) rifle slug it's more likely to penetrate than a .38 "wad-cutter" (flat faced).
But, you have to keep in mind that punching someone with your fist is 100-300 ft/lbs of force. A punch can be lethal. But, when someone holds a knife in their hand as they punch (or uses a crow bar to deliver the punch), we don't usually call it a "punch."
That's my only concern about celebratory gunfire. It's like the media's new titalating topic. But, the vast majority of deaths and injuries that I've seen reported weren't bullets falling out of the sky. They were lateral shots which still had significant forward energy as gravity pulled the bullet to the ground.
said by GadgetsRme:Be my guest step in front of it. I don't recall anyone saying they wanted to be hit by a falling bullet. Nor that firing into the air is responsible behavior.

I hope it tastes like chicken.

Yes however even a slight curve is deadly, and people tend to drink so they don't always shoot strait up intoxicated. (I do own several guns but hate people who shoot guns for new years.)

(I do own several guns but hate people who shoot guns for new years.) Maybe you're defining "slight curve" differently than I do. But, 5-10 degrees either side of 90 (straight up) isn't going to produce any more lateral motion on the falling bullet than the normal air currents will.
If you're talking 30 degrees away from 90 (straight up), then I agree. It will still have significant forward energy as gravity pulls the bullet to the ground.
Again, I'm not trying to say celebratory gunfire is harmless or tolerable. I'm just sensitive to the definition because I keep seeing news stories of a bullet that entered a home's wall and struck someone 20 feet away from that entry point. That's not a falling bullet (the way the news depicts celebratory gunfire).
I just get tired of the news ascribing magical, anthropomorphic powers to anything related to guns. I'm expecting a story about how someone in NY shot into the air and it killed someone in CA. I'm surprised guns don't randomly discharge by themselves!

I remember that one! It was actually really funny to try and get projectiles to come straight back down.
Mythbusters again!
However, they never tested the added forces added on if it was a lateral shot. I agree with the first post. A bullet coming from the sky "probably" will not kill anyone and it is more likely gunshots coming from an angle (directly fired into homes) will.
I think fireworks are just as likely to kill someone.
With irresponsible use, you have someone firing explosives into the air (which can go anywhere). You can start wildfires, home on fire, or blow a little girls head off.
Lets not shoot our guns off, k? |
