The rotation of the earth comes in play when shooting up .........don’t forget where we are in our orbit around the sun, southern or northern hemisphere, position in the universe and so many, many more variables😄!! PennDog

And the bullet will maintain its alignment from the point of firing thanks to the spin - firing at any angle apart from straight up means it will be travelling sideways downrange and be subject to tumbling as a result. At no point in time does the bullet "travel sideways".

You fellas get bored find a copy of Modern Exterior Ballistics by Robert McCoy, pour some coffee and start reading.

My brain is definitely traveling sideways . I'm confused as hell ! 😫

The rotation of the earth comes in play when shooting up As well as the direction of the rifling.

mag410, I was told it was a .22, it could have been a .458 Win. Mag. shooting up in the air, with anything but a shotgun is not smart. Rio7

And the bullet will maintain its alignment from the point of firing thanks to the spin - firing at any angle apart from straight up means it will be travelling sideways downrange and be subject to tumbling as a result. At no point in time does the bullet "travel sideways". The spin keeps the bullet spinning on a fixed axis - it could be going sideways down range, or if disturbed it will tumble out of control. The spin lasts a long time - in most cases it's still spinning when it hits the deck. There's minimal resistance otherwise to slow the spin. There's video of 9mm bullets fired into ice and they keep spinning. Mythbusters did this too.
Whatever you said...everyone knows you are a lying jerk. That's a bold assertion. Point out where you think I lied. Well?

Spinning keeps it in the aligned axis - what makes it change it's axis in flight and stay stable? Like holding a spinning bicycle wheel in your hands and turning in one direction gets a reaction in the third axis.

For example, a bullet which is overstabilised will tend to remain aligned with its angle of departure, rather than "nosing over" to follow the trajectory as we get out to very long range. There are also a number of forces at play tending to cause a bullet to yaw in flight, and not just at very long range, and bullets will tend to drift sideways as a result of wind and spin drift, among other things. There's a rather good treatment of these questions a fellow named Ruprecht Nennstiel put together a while back : http://www.nennstiel-ruprecht.de/bullfly/

You fellas want a different path for critters up in the trees maybe give this some thought. They are 100% effective on head shots....and don't travel 1.5 miles if you miss....and don't tumble. They won't wash your truck however. If you got it all figured out they are fairly accurate at close range.

"Yaw" is a wobble back and forth along the axis of travel and it's center of gravity. It doesn't mean the projectile is traveling sideways Wind drift and rotational "drift" don't mean the projectile is travelling "sideways" in regards to the direction of it's intended main path.

It might be flying 'tip up' on the descending arc.
If stabilization is just perfect, it should 'tip over' as it begins descent.
If excess stabilization, it may fly tip up in descent, not unlike a football with lots of spin.

I always wondered how many folks on the ground got hit by empty 50 BMG and 20 mm cases during the big airbattles over Europe during WW Twice. Seems like a lot of empties got spit out of fighters. Not to mention all of the falling aircraft and the bullets that came out of them as well.

Not to mention all of the falling aircraft and the bullets that came out of them as well. My old stomping grounds in NM was literally riddled with spent 50 cal brass as well as bullets. You could expect to find many of both when horseback there at the ranch in a day's time. Also found several linked ammo belts from the aircraft with live ammo. I suspect they kicked them out for a reason... Maybe they were tired of shooting practice, and couldn't return until the ammo was all gone, so they kicked out belts of live rounds to shorten the flight time. It was always interesting. Most brass stamped '41-'43. Our ranch was an old air force training range. It still has the earth targets visible from satellite image. One canyon was inert bombs, and another was live bombs. You could sit anywhere in the live bomb canyon and reach out and pick up a jagged piece of shrapnel. Salvaged many inert practice bombs.
