Bullet stabilization, strictly RPM?

[QUOTE="sambo3006, post: 168153, member: 2740"] Let's say that you have two different cartridges like the 6.5-284 and the 6.5 STW. Also assume that the same bullet is being used like the Berger VLD 140. Lastly, assume that the rifling twist rate on the two barrels is such that they both spin the bullet at the same RPM--faster twist on the 6.5-284. Is the bullet equally stabilized by each cartridge due to the same RPM spin even though it is most likely traveling at 300 or more fps faster out of the 6.5 STW? Will either bullet lose its rate of spin faster than the other in flight? I realize that the bullet from the 6.5-284 will slow to transsonic first, I'm talking strictly supersonic. [/QUOTE]
