once the flame is adjusted to its set point, the case neck exposure time in the flame should be very similar. Less than one second variation, in my opinion.
Yes exactly. 6-12 is a ballpark range for my basic Coleman fuel torch on medium and it's given as a reference range. It's enough time for me to be able to see the change. 6-7 seconds for .223 class, up to 12 for 300win mag class cases. At least that's been my successful experience. I included a pic in the last response of a 257 bob case annealed on left next to non/annealed on right. I included a pic of my socket heat sink that helps keep the case body/heads from heating also. It works pretty slick.
