How does barrel "twist" relate to projectiles and accuracy?

Barrel "twist" is what physically spins a bullet and stabilizes it. There is a big difference between the twist required by a RoundBall and that reqiored by a Conical. Round balls require a very slow barrel twist to achieve optimum accuracy. Barrels with 1/60", 1/66" or even 1/72" twists are common. For conicals, a faster twist is required to stabilize the projectile. 1/38" or faster is common for conical barrels. For sabot loads, even faster twists are required. 1/32", 1/28" and even 1/24" are used for sabot loads.

The single most popular barrel twist however, is the 1/48". This is a compromise twist being neither great for conicals nor roundballs. This is not to say good groups cannot be achieved with such a barrel twist, just that it will never be as accurate as a rifle who's twist is optimum for it's load.
