If you have a lead hardness tester please get in touch with me.
I’m going to try an experiment to gauge the accuracy and variances of various lead testers on the market. I will be looking for a certain number of people with various types of testers.
I realize this experiment has been done in the past and is published on the lasc.us website, but would like to expand on their test because the number of testers used was inconsistent between brands and fairly limited. It is my desire to get results from a greater number of testers, to be able to make comparisons between brands and check for consistency within brands. I have access to a machine that gives me pretty tight control over constants tied to the production of the bullets, so hopefully I can eliminate most, if not all, variables outside of the specific tester and operator combination.
Here is what I am asking from you.
1. Send me a PM with the type of lead hardness tester you have.
2. I will choose a similar number of each type of testers, and ask those people for their snail mail address.
3. Using a commercial grade machine I will cast a bunch of bullets using a consistent speed, alloy, temperature, and time to quench.
4. Sometime after 21 days from the cast date I will mail you ten bullets.
5. On a given day specified in the letter that comes with those bullets I will ask you to test the hardness of all ten of your bullets with your lead tester, and email me the results.
6. I will post the results on this website, linking measurements taken to tools used to measure.
In order to encourage a wider range of participants, I am posting this request in the reloading sections of the following websites that I lurk or post at. Please respond to me via PM at only one of them.

I’m going to let this float for a while to see how many of you would like to participate, and then I will send out bullets to be tested on an equal number of tools. I am probably looking at another month to a month and a half before I actually get bullets in the mail, if all works out as planned.
If you can think of anything that would eliminate any variables I haven’t thought of please drop me a line.
Also, if you’ve got a link that can convince me that this experiment is a waste of time please forward that as well. Remember, I am concerned with the accuracy of testers, and the consistency of results obtained by their users.
Thanks.
