Twists of Fate, and Rifling (Weaponsman)

Twists of Fate, and Rifling
We’re not sure about twists of Fate, but a number of you have asked us about twists of rifling. The question usually comes in the context of AR-15 rifles and their clones, with rifling twists of 1:14. 1:12, 1:9, 1:8 and 1:7 all having been used.

Can you calculate optimum twist for a given caliber and projectile? Yes, you can. There are two equations that are commonly used, Greenhill’s and Miller’s.

Henry Kissinger said, "Military Men are just dumb, stupid animals to be used as pawns in Foreign Policy" and has not denied this quote to this day.
