Fascinating post
The rub is of course, no matter how hard you try you can't keep all the variables constant while you manipulate rate of twist.
Some of the posts are very scientific and I really appreciate that. The Litz test (I think that is what it was) and Elk's last post may be showing that the small difference in MV moves the point of impact due to harmonics not bullet stabilization.
I calculated the rpm of bullets exiting the barrel once and they were extremely high and it is hard to believe that a higher rpm makes them more stable.
Maybe the different twists rates are just a marketing tool? As others have said, its how they shoot that counts.
Good stuff.
