Thank you for the reply. It sounds like you use the 9/16” socket as a heat sink in similar function as I use my rotating water pan.

I also pay attention to the color changes, but I notice that I get different color changes when I change head stamps. For example, I notice that color changes on my LC brass is harder to see than on commercial head stamps. So I felt that I had to experiment with the Tempilaq to find out what’s going on with my brass. I don’t use the Tempilaq any more now that I feel comfortable with it, but I think I’ll do it periodically to make sure everything is still going well.

Main reason I still anneal with every loading is that I saw something that implies the Lee collet die works better with annealed brass. Can anyone confirm whether that’s the case?
