[QUOTE="SWHandldr, post: 2396672, member: 114858"] Don't know. Getting the brass that soft would require heating it well beyond the 'just beginning to glow' stage. I'd reason that it might be possible to get the mouth that soft without melting it but you'd likely be right on the edge of melting or deforming it. That's way beyond an effective anneal: One that helps make seating tension more consistent, reduces ES & SD, relaxes the work hardening of sizing / firing and increases brass life. Our goals in annealing. Time and temperature BOTH matter, according to Reese (guy in the videos). A metronome if you're flame annealing on a budget or an electronic timer in more costly flame and induction devices provides control and consistency. Heating a case mouth to the point that you could distort it by hand has to be more than the difference in six seconds instead of five (a 20% increase). WAG it's around double the time, so a gross change. You don't have to go that far to achieve an effective anneal. You can download a metronome app to your phone for free. Once you've established a time that heats the neck & shoulder to dull red - regardless of the heating method - is there any reason not to use some kinda timer to improve process consistency? I can't think of one. So serious question: Why would anyone heat cases to the point that the case mouth can be distorted by hand? Edit 11:58 am: Grammar / clarity [/QUOTE]
