Maybe we throw differently,
Either way, distancing from the football as a couple hundred RPM is nowhere near the couple hundred thousand RPM of a bullet.
My post is that bullets tend to travel along their trajectory with a nose up angle (Angle of attack) as the gyroscopic spin keeps their longitudinal axis more or less parallel to the line of departure.
there are many more forces in play as well, like gyroscopic precession, but that is another topic for much discussion.

I am not trying to contradict yours, it was just a clip with an upward attitude along a flatter trajectory.
I think we might have crossed into arguing the same point?
It is very interesting learning about and discussing external ballistic factors.
I just fell down a rabbit hole about nutation.

There was no indication of how that football was thrown. If I had to guess, it was underhand.
When I throw a football properly, it exhibits balanced flight, like the video I linked.
:43-:54 full flight from release to catch.

I'm glad you guys are so interested in nitpicking my crude Microsoft paint diagram, next time I'll use AutoCAD and more then 30 seconds to make it.... 
My point still stands, the bullets are not tumbling and the consistent angle of impact indicates no excessive yawing.

Since this thread has been iredemiably skewered long before you guys started on how a football flies and how a bullet flies, could someone please explain what the football/bullet debate is about.
Is someone suggesting that a football in flight doesn't spin on its axis along the path of its trajectory?
Is someone saying that during a bullet's flight it doesn't spin on its axis along the path of its trajectory?

I apologize in advance for not following what you wrote. Is there another way to explain what you said? Are you saying the front end of the bullet -- the tip if a .22LR bullet was pointy -- doesn't always point in the direction it's traveling? Or is it something else altogether?
grauhanan, getting back to one of your earlier questions,
what if we put that chipmunk in a vacuum? Would that improve it's accuracy throwing acorns as compared to throws made in standard atmospheric conditions? What if the .22LR bullet was cube shaped? or pryamidal? conical?

I have to admit, I skipped a bunch of pages but can ascertain that Covid has had an impact on more people than I had originally thought!!! BUT seeing as how I have you all gathered here together, "if a Biathlete fell off his bicycle while riding in the desert, how many pancakes would it take to cover the surface of the moon?"
Thank You.
Thank You.
Yes, in a sense.
Best way to explain it, is that (we are making some assumptions about bullets leaving the barrel in a perfectly straight line with the tip perfectly in line with the bore)
the spin imparted on the bullet by the rifling caused Gyroscopic stability.
As gravity affects the bullet, the bullet follows a trajectory in an arc.
however, the tip of the bullet, due to the gyroscopic stability will have an increasing angle to the flight path (known as angle of attack)
- I should note that we are talking about stable flight, ignoring the trans-sonic barrier and other non-stadard aerodynamic forces for now.
Thats my only point.
If a chipmunk were in a vacuum, he'd either starve or axphyxiate. Veterinary science and medicine has determined that the type of acorns chipmunks like best would self-crush under the absence of pressure, rendering any nutritional and ballistic value moot.
On the other hand, sophistcated work at the well-known secret Sellier & Bellot testing facility in the Czech Republic show that when these acorns are used by these Chipmunks, the results are often a higher than average BC and lower than average ES and SD -- if the range is more than 100 yards. The reverse is usually true at shorter ranges.
A slingshot with acorns generally produces superior ballistics and long range accuracy. When the shooter does his part, with acorns his slingshot likes, he can easily outshoot a Chipmunk. Probably kill or maim it too.
