Why do some of these bullets have recommended twist rates?

Long-for-caliber bullets (i.e. .22-69gr, .22-77gr and .22-80gr) need a faster twist rate in order to stabilize the bullet.  Long-for-caliber bullets yield much higher Ballistic Coefficients making them popular with long range enthusiasts but they do require fast twist barrels in order to stabilize and shoot accurately.  For example, a 22-69gr Custom Competition™ bullet requires a minimum twist rate of 1-9” to reliably stabilize and the heavier/longer 22-77gr bullet requires a minimum twist rate of 1-8”. Both of these bullets will stabilize with even faster twist rates (i.e. 1-7”) but not slower.
