[QUOTE="trebark, post: 1560891, member: 19172"] Test COAL the same way you test charge weights. Hold the charge weight constant at 88grains of H1000. Then load three or five rounds each of .002", .010" and .015" off the lands. (you have already tested .005"). Go ahead and run every round over the chrono (shooting without a chrono is like shooting with your eyes closed). Then examine each group and see if there's any kind of a sweet spot. Given that you are shooting the berger hybrids, they are not particularly depth sensitive. So you should not have a big problem finding the optimal COAL. Once you have the optimal COAL, then start working on charge weights. [/QUOTE]
