Art,
That's very interesting!
I ran the numbers through the Miller computer program, and it came up with a stability factor of around .8--which isn't anywhere close to stabilization. While the program isn't a perfect prediction of stability, the number normally has to be a lot closer to 1 for a bullet to work.
One possible explanation is the bullet length, taken from the Barnes website, may be off. If you have some of the 80 TTSX's handy I'd sure like to find out the measured length.
