While I was in one of my meditative postures (??!!) I got to wondering .... does the rotational speed of a bullet decrease as velocity decreases? I realize there is probably only a fraction of a second to a few seconds until impact and subsequent zero RPM, but what do you think? For ease of figuring I use 3000 FPS and 1:12 twist and arrive at 180,000 RPM exiting the muzzle. Not that that really matters.
Not firearm related, but a previous question in my mind: if there are enough wind turbine generators in a line extending downwind, do they eventually "use up" the wind the further downwind they go? I know, I just have too much time on my hands .... only looking for lighthearted answers.
Should have been clearer in my wording; more like, when a bullet fired at MV of 3000fps slows to 2000fps (for example), does the rotation decrease correspondingly? Again, not seeking an agonizingly detailed answer, just one of those "Hmmm, I wonder..." moments.
