So I'm on load number 9 and I started thinking about having to reform some new brass for my 243 AI and read an article about annealing cases. Check it out... http://www.6mmbr.com/annealing.html I liked the last part of the article. After reading this I decided to give it a try. I chucked up the shell holder I have for my k&m neck turner and grabbed a torch I had laying aroud. I turned the drill on and spun the neck right at the tip of the blue flame that is about an inch past the end of the torch. I held it there for about 5-7 seconds. Basically right when or right after the flame changes to orange and the neck almost appears to start on fire. I then push the neck into water and the case head is only warm due to conduction. I think I'm doing it correctly and the necks seem to be noticably softer. Anybody that has experience annealing necks have any comments or suggestions?
