BHs of all the common bullet alloys are listed in Joe Brennan''s book. The CBA has sold hundreds of copies so lots of them are in forum member's hands. Joe never took a penny of the money.

I am away from home and my copy but many on this forum know the answer to your question. Joe's book is also on line.

On our own downloads page is a link to a Lead Alloy Calculator. An indispensable tool for bullet casters.

Pat, Sorry, I don't. Since I bought all of Joe's edlions as they came out, I never needed to. Now I regret that I didn't find out while Joe was still alive.

I've mixed up numerous batches of 30-1 alloy with the BHN measuring 8.5 - 9.

I remember sending Joe Brennan some of John Alaxander's 80 grain bullets to try in his 1/14 twist rifle. The bullets were cast using 20/1 lead tin alloy and shortened gas check shank. Joe was excited to see, but was confused why they shot very well without tilt...nobody could explain why. His thoughts were WTF?

Sorry, you have to buy the physical book from the CBA. No electronic edition.

Joe made all his books available for free on the internet before giving the CBA permission to print and sell them. The CBA had nothing to do with the books on the internet. I don't know how that sort of thing works but I assume that when Joe stopped maintaining his web page they are gone.

Is there a way to make something stay indefinately available? If so the books are probably there somewhere.

This may help for others in the future since it contains many of the more common alloy & components info:

When you stop paying for your web page, everything disappears. I saved Joe's page link, but when I clicked on it last summer I got the "404 page not found" message.

Ric, You might try using the "Internet Archive Wayback Machine" to find stashed copies of the website and related links. I used that a few times in the past & it works quite often.

Thanks to all. From the info provided, it seems that a mixture of equal parts lead and clip on wheel weighs should give me about the same hardness as 30 to 1. Am I correct? I have a lot of lead and WW's and precious little tin.

It looks like it would end up around 8-9 bhn depending on the exact composition of your wheelweights. The alloy will likely vary a bit in performance from 30:1 because the elements are different. WWs have antimony in them and 30:1 of course does not. It all depends on how you need the alloy to perform on target. For general shooting you should be just fine.

One other easy way to get an approximate bhn on an alloy is to go to Rotometals and click on their listing for that alloy.
