Bullet stability is a topic that seems to have many long ranges enthusiasts chasing their tails round and round. There are a number of dynamically interrelating factors that play off of each other in various ways resulting in a bullets overall stability or instability. Whether you are using the Greenhill formula, the Miller formula, or McGryo's mathematical monster - the full story of any bullet's stability characteristics is incredibly difficult to express on paper.
Twist Rates: Determining which twist rate is most appropriate for a given bullet is the big question here. One can get a basic idea as to the predicted stability trends a particular bullet may display when fired through a certain twist, but the only way to know for sure is test it in the field. Often, bullets that should be too long and heavy for a given twist work great while other bullets that should have been easy to tame are going wild. Most manufacturers publish their recommended twist rates for their different bullet tests, so this may be a good way to go. If you don't know what twist would be best, you can try one of the formulas to get a basic estimation.
