‘At dead soft you will have ZERO neck tension to hold the bullet.”
I use an induction heater to anneal brass with and have been trying different shades of red to determine the temp I want the brass. I have taken it to red all the way down into the shoulder and still have plenty of neck tension to hold the bullet. Now to qualify that statement, this is on LC 5.56 brass cases of recent manufacture, and they feed and function in an AR-15.
My PPC and Beggs cases are taken to a slight glow in a low light setting which I’m sure is still well over 800 degrees, and have not seen a reduction in case neck tension.
Now, I don’t claim to know the best way to anneal brass, my reasoning to do it this way has to do with repeatability and time. It takes about 14 minutes to do 100 pieces of brass, and that’s at a leisurely pace. Still, I want to learn what others are doing and why. I have found that with annealed brass, my headspace can be adjusted to the .001 with virtually no spring-back, yet I’m reading that dead soft is not the goal. I’m not up to speed with you guys, so please help me along a little.
