Bowace....I really dont understand what you are asking. What is the most accurate of the 3 WSM cartridges? What caliber bullet is more accurate?

With the 30 caliber bullet being probably the most popular made, you have the widest selection to choose from. From a true accuracy standpoint using match type bullets, the order would be .308, .284 and way down on the list the .277.

Unlike Vapodog I would say that cartridge design has alot to do with accuracy. The new short/fat designs such as the WSM' s are derived from the 22 and 6mm PPC' s. They tend to optimize burn efficiency, making them very consistant. If cartridge design dosent matter why is the 6 PPC considered the most accurate round ever and not the 243 Win. ?

just my thoughts....AA
