Annealer
As I said, this is more of an announcement than a how-to video, but if asked I'll put links in to the pieces such as I can find them again. All Chinese stuff from Amazon or nearly all. The big surprise for me was that it takes longer for lighter (assumed thinner) brass to reach temperature.
I haven't yet shot any of this super-uniformed brass to check accuracy, and I'll be doing the old (often ill-advised) matrix of testing more than one thing at a time, since I'm also now wet- tumbling with stainless steel and citric acid, rendering the insides shiny again. A theory being that this affects the initiation rate of the gunpowder....we'll see. I'll report results when I have them.
