As far as I can tell from reading various posts of experiments, the LBT hardness tester may be about the best for measuring Brinell hardness of bullets. I wonder if anyone has tried to use a Rockwell tester. I know the lead alloy industry uses Rockwell "R" scale and the bearing industry uses Rockwell 30X scale. Because the R scale uses a 1/2 inch ball, it is not well suited to small samples. The X scales use a 1/4 inch ball which is a better fit for hardness on a meplat. Anybody doing this?
