I really was not trying to beat you out of any of your stash.I just looked at my chart and it shows 20-1 to be 10 bhn. Did not think about the chart until now!

I'm not at all concerned about a thumb-sized piece of alloy out of my 'stash'.Originally Posted by lightman

Which 'chart' are you referring to?
The 'published chart' that is found on a lot of sites ... or a chart that is supplied with your tester?
I know that all of the published charts say that 20-1 is 10 BHN, but that happens to be wrong.
I am more interested in knowing what the Cabine Tree tool returns as the hardness of 20-1.

Got my Cabine Tree in yesterday, and have tested everything I could get my hands, but I have a question.
I tested some SOWW and they come up to 5 on their chart.
My question is on the lead calculator on this site, says SOWW are 6Bhn,but when you put in 1 LB in the SOWW, at the bottom it comes up as 8.7.
What gives?
BTW, I'm extremely happy with the Cabine
The '5' returned by your tester is a whale of lot closer to real life than the 8.7 in the formula for those 'calculators'.
They cannot even give you a ballpark guess on any lead/tin alloy.

You are correct at 5.
Contact Bumpo (tha author of the spreadsheet) on here and he will explain why the 8-ish is in there. If it is not , the sheet is not accurate at all. After all, how many times do you need to calculate the hardness of pure lead with a spreadsheet!!!!!!!!!
The sheet DOES work quite accurately when you have several elements mixing in.

Montana Charley, That was from a sticky at the top of this thread. I've found that chart to be useful. I wish I had some actual 20-1 to test. I don't know enough about it to know if 10 is correct or not.
I gottcha.
Thanks ...

I've been using the LBT tester regularly for at least twenty-five years; seems to work very well. I'm unfamiliar with the other testers mentioned here.
Have you checked out this test...

My LBT tester is easy to use, and provides a fast reading. Maybe not as flexible as the Lee, and I have no experience with CT, but LBT is my recommendation...

Spare dial indicator and a torque wrench on sale at Harbor Freight for 10 bucks, it could be a lot simpler based on your resources- http://castboolits.gunloads.com/show...in-Lead-Tester
