958.6207 ft/s (653.6128 mph) is the terminal velocity of a 150 grain 54r bullet
nearly 1000ft per second is perfectly capable of breaking light pot steel of a 5.45 round.
if you disagree prove me wrong i used this calculator....
https://www.gigacalculator.com/calculators/terminal-velocity-calculator.php
Terminal velocity is a range, between 40 and 150 m/s (it could be a little more) due to AA, a free falling bullet isn't stabilized. And that ignoring any residual horizontal component of the initial velocity.
look at the bullet, and look at the base of the 5.45 case it's embedded in. The 5.45x39's base is 10mm, and the bullet is a little bit less. It's not 33% thinner, it's more like 10% thinner. It's a 9x39 bullet.

Also, what's your take on how this happened, assuming it's not fake?
how much velocity do you think is needed to break the cheap thin steel of a bullet casing? im not figuring out the material resistance to impact and sheering resistance for this argument......22lr ammo will go through an old car door fine it will go through the 5.45 side wall....half way....easily
>22lr ammo will go through an old car door fine it will go through the 5.45 side
And those cases are relatively soft steel yet over stressed by forming, the 7.62 is heavier vs diameter.
Probably it's incorrect for this case but according to de Marre the pen would be around 0.2-0.5mm as min (40m/s) to 1 mm as maximum (150m/s).
A bullet does not settle point down into a fall. That requires spin imparted by the rifling that has stopped at the peak of ascension. The terminal velocity of a 30 caliber is much slower than you figured and is in no way lethal to an adult human being.
Make some claim on its velocity?
What I can tell from the picture is that bullet was not shot straight up. It was not falling at its terminal velocity. It also seems like there were some other unknown factors that make it very hard to determine how fast it was going.

the argument is that is could not have been.
in all likely hood it was not shot straight up but forward.
but had it came from a vertical shot and arced in air it still assuredly would be able to pierce the round.

All shots other than vertically shot are arcs. The vertical or actual shot straight up do not return stable. You have zero idea how much force this would take as you are without several metrics. >>shut the fuck up retard.

What we do know is the entry and travel suggest this was a stable round.
Not when it's fired straight up as was suggested, as was being discussed.
You are talking about when traveling in an arc. And even then, no. When enough energy has been spent and the spin has slowed too much the bullet is no longer stable in flight and will do many things depending on its design. >>you don't know, so you should shut the fuck up because you sound all retarded and shit.

Even when fired straight up the spin is maintained.
It is separate from the vertical vector and completely unaffected by the velocity of the bullet once fired.

Bullets must be spun at the correct revolutions. Over clocked fast enough and they become unstable. Too fast and they can blow up. Happens in testing all the time. Under clocked and they are unstable.
In flight the revolutions slow and can get to the point while still in flight that certain bullet designs become unstable.

It absolutely does slow down. Testing with live rounds has already shown that bullets fired vertically and near vertically land unstable. Key holes if you will. Testing on long for caliber high SD bullets have shown them to be unstable at max ranges as well.
You are making restart level claims that do not take into account original spin rate, bullet design or the fact you are a larping clown who probably namefags on the side

Except that's theoretical and is not what happens in actual testing. One bullets are not well balanced, that is why they require spinning to fly point first. Secondly you have never owned a top, football or any other thing that functions exactly on the same principles or you wouldn't make asinine claims.
In the real world this test has been performed many, many times. When a bullet shot straight up or even near straight up, they come down unstable, unpredictable and non lethal.

It was literally proven during Hatcher's ballistic test. He also noted other testers had the exact same results.
Without other factors working on the bullets come down still spinning and in the same orientation as they went up.

Even at constant spin stability varies with velocity, long bullets can tumble when they go transonic and are less stable below speed of sound.

How narrow is that window? I get the impression you could very accurately predict the speed of the bullet for something like this to happen

It actually hit the casing, not the bullet.

It did, that's why they're stuck together.

Looks like it got shot

nope
It definitely is from a 9x39, that projectileis definitely bigger than a 7.62x54r ball
A 9x39 is too short and the proportions are off.
It looks like a 7N13.
