[QUOTE="Buffalobob, post: 413483, member: 8"] Bullets are designed differently to do different jobs. Bullet stability affects what a bullet does after impact and you should decide up front how you want the bullet to behave and get a barrel twist that provides the spins you wish at the ranges you wish. When considering spin and impact behavior you can loosely segregate the bullets into two designs, nearly symmetrical and asymmetrical. You then must subdivide those into expanding and non-expanding bullets. Stability is achieved by different means for the different bullets and spin may be of little importance in some of the categories. Even in the same category more spin and less spin will give you different results upon impact. At extreme ranges less spin may well be a better choice however even then the cat may be skinned by excess spin depending upon other factors of bullet design. [/QUOTE]
