I use 650F under the shoulder/case body junction. I don't want to remove tempilac from the inside of the case neck... the liquid makes a horrid mess.
Crayons can't get in there effectively.
With the tools we have, it is more "goldilocks" then science. Better to be a bit under then over annealed. The goal is to be consistent and ductile enough to give consistent neck tension. As long you can be consistent from case to case and from run to run, that is all that matters as you will load tune to that neck tension.
But if it varies all over the place, better to not bother and toss the cases then try and chase these ghosts... Been there, done that. You can create more problems with irratic annealing then shooting work hardened cases and tossing them when a few split.
When you use gear that allows you to vary the dwell time in very small increments, you quickly see that too much is not much longer then just right. And many annealers out there do not have very precise or consistent "clocks" so this can also create problems. See my website for a very nice unit with poor clock... hopefully, corrected by now????
The Bench Source is pretty much the gold standard of what we can get in Canada. Some are testing induction annealers which have their own pros and cons.
Neither is cheap but work out the cost of ruined brass and/or irratic accuracy with very expensive match bullets and powder and primers... not to mention eating up those nice barrels.
Just depends how far down this rabbit hole you want to go...... on the upside, I really don't see how my Bench Source is going to die so given the lifetime of properly prepped brass, it is a very small investment.

PS brass condition has a big part on how hot and how long... so test and see what is best for the brass you have and then what you need to do to maintain. FAR easier to keep to a regular routine then trying to restore really work hardened cases.
