of a tour of BAT Actions this morning. Interesting stuff, almost all CNC. Surprised they do their own heat treat, or at least some of it. The shop was smaller than I imagined it would be.

Great video.
I would suspect that the reason they do in house heat treating is because there is very little available in the way of 17-4 at the strength level they require.
