[QUOTE="Greyfox, post: 636688, member: 10291"] You are right, this does go against convention wisdom, but then again the author applies fairly sophisticated formulas that take into account a lot more than just length and bullet weight. Size, velocity, shape, air density, etc. I think the practical aspect to the charts shown in the book is that if the twist rate exhibits a stability factor of at least 1.4, it is likely to be stabile. From the data shown, some bullet designs must be better than others irrespective of weight and length. [/QUOTE]
