Lots of threads on this topic lately. Thanks for those measurements. I have only shot handloads so I didn't know the factory COALs. Those are close to the measurements to the lands I took in my 16" AA Lite chamber I just got in January. I'm going to go with it because it shoots good if I load to stay about 10 mils off of the lands. I'm still experimenting with the jump distances. My measurements are shown in the picture below.
