I was writing for the various gun magazines rather regularly up until about 1990. I stopped, somewhat unintentionally, because I started working on an article idea that just took a great deal of time. The idea was an Encyclopedia of bullet casting. Now, 22 years later, I've finished and am in the process of writing all this material up.
One of the areas that I am not going to cover, because I'm not really interested in it and know nothing about it, is heat treating of wheelweights. Wheelweight bullets will be included in great detail but I'm not going to address the subject of heat treating them. I would, however, like to include references to how this is done.
So my question is this. Are there any references I can site that would cover this subject?
