I have a new Lee hardness tester and I'm not sure of the answers I'm getting with it. I don't have any "known hardness" alloy to use as a baseline.
I tested ingots, not bullets; on an ingot of dental x-ray lead foil, I read about an 8.2. An ingot from a source that described it as "nearly linotype" I read about a 12.
Lee's instructions for testing a boolit say to file a small flat on the side of the boolit; in the case of water-droped slugs is the hardning just a surface hardning of does it go deeper?
And lastly, what hardness should I be looking for for boolits destined for a studly .41 mag load?
