Lol...no...I admit I was partly wrong. In that while falling bullets are certainly highly unlikely to be fatal, it is possible if all the variables align correctly.

I would contend they are a bit more dangerous than I first thought, but certainly not as dangerous as the initial stats you posted implied....for bullets propelled only by gravity.

A bullet fired straight up on Earth, assuming there’s no wind, might still be able to reach a maximum height of around three kilometers (about 10,000 feet), and will then fall back down to Earth. However, just like a human skydiver only accelerates for a few seconds before reaching terminal velocity, the air resistance acting on the bullet will prevent it from reaching speeds even close to muzzle velocity ever again.

Instead, a falling bullet comes back down with a speed of only around 150 miles-per-hour (241 kilometers per hour), which is just 10% of the speed it was fired with. Because of how energy works (proportional to your speed squared), a bullet that falls from high in the air only possesses 1% of the energy of a bullet newly fired from a gun: the equivalent of a brick dropped from a height of just 50 cm (about 20 inches) off the ground.

In terms of speed and energy, this simple treatment does, in fact, correctly give us the properties of a bullet fired up into the air when it hits the ground. But in terms of location, bullets that are fired even straight up can actually come back down up to two miles (about three kilometers) away from where they were fired.

A 150 mile-per-hour bullet won’t be lethal in most instances, but there are two factors that can change the equation dramatically.

Bullets that are fired at an angle, rather than straight up, may never stop and begin tumbling; instead, they can maintain much greater speeds: many hundreds of miles-per-hour.

If a bullet has enough speed to break the skin, it can potentially be lethal; this occurs at different speeds for different bullets and different individual people.

You must be allergic to physics and common sense...

If they were seriously injured, it was because the bullets were not fired straight up. They might have been on a downward trajectory, but were still carrying velocity from being fired.

If you doubt this, it is very easy to calculate the energy of a...say...125 grain bullet falling at terminal velocity. You will find it is a tiny fraction of a bullet's muzzle energy, and insufficient to cause serious injury, if the bullet is propelled purely by gravity. That is the point of this discussion, which you missed.

Or, you can continue to make pouty/petulant little arguments with little or no bearing to the topic being discussed. I'm sure that's easier.

So many people misunderstand this. A normal sized bullet falling on your head....from any height....would certainly hurt and might draw a bit of blood, but won't be fatal.
