[QUOTE="Michael Courtney, post: 908290, member: 28191"] The maximum spin rate (RPMs) does not only depend on the bullet, but also on how much the trip through the rifling weakens the jacket (scoring). Consequently, it is as much dependent on the rifle it is fired from as on the characteristics of the bullet. One rifle with sharp rifling might have a much lower RPM to cause the blue streak than another rifle that does not score the bullets as much. [/QUOTE]
