wow, did some more calculating and lots of good replies
ran a 240SMK at 2500fps in a 10tw and got 1.55 stability factor.
there is absolutely no need to go 9tw.
you can over spin but you want to have the best stability for what you're shooting under the worst conditions(temperature/elevation). Run a few bullets in the formula.
