Re: Bullet stability factor: big deal or not
Stability does not decrease over time. It actually gets better until it hits the transonic zone, then destabilizes (much of the time anyway).
Also, other bullet makers dont offer that info because they make traditional bullets that will stabilize in traditional twists. Although, Sierra makes note that certain bullets will need a specified twist to stabilize.
Long range shooting is a process that ends with a result. Once you start to focus on the result (how bad your last shot was, how big the group is going to be, what your buck will score, what your match score is, what place you are in...) then you loose the capacity to focus on the process.
