I read somewhere that all Winchester black powder bullets were 20 to 1. I have had luck with 30 to 1 in my Trapdoor, Jeff in NZ has mentioned using 40 to 1 in some of his efforts. Is there any way to convert these mixtures to BHN? I have lots of WW but not as much lead as before.

Thanks in advance

Try this link.  It is for the Carnagia/Cabintree hardness tester chart. Shows their readings and Saeco test unit readings.

With rifle in hand, I confidently go forth into the darkness.

Also for comparison, app. BHNs are listed on RotoMetals website under the different alloy mixes.
