[QUOTE="J E Custom, post: 1266405, member: 2736"] +1 But you need to know because it is controlled by the reamer used. SAAMI chamber dimensions for the 300 WSM show that freebore is .189 A chamber cast is the best way to measure freebore. The case length is/should be 2.316. If you try different bullets you will get different dimensions and the freebore length and throat will still not be correct. Measuring COAL using a bullet will only tell you how far you are off the lands or when you contact the rifling. J E CUSTOM [/QUOTE]
