Ok. I have several friends whom I have been talking with that have disagreed about this topic yesterday. I will ask the main questions here in a way as to not "steer" the answer so I can't be accused of wording the question in a way that leans the answer in my way of thinking. I will not say now what I believe to be the answer. Ok, here it is: If a bullet leaves a barrel that has a 1-8" twist, is it still spinning 1 time in every 8" all the way through it trajectory say out to 1000 yards? In other words, if we viewed the bullet at the 786th yard and followed it in slow motion throughout that yard, would it still be revolving 4.5 times in that yard? (lets assume the bullet has no flaws in the outer surface of the jacket, and there are no voids inside the bullet) If you were to shoot a 55 grain bullet out of an 8 twist barrel at 4000 fps, and then shoot a 80 grain bullet out of the same barrel at 3000 fps, they have different rpm's, but do they both still spin 1 time every 8 inches?
