Did you build your own annealer, ala gina eric style? If not what are you using?
What cases are you annealing?
Put the tempilaq on the outside where you can actually see it on the neck down past the shoulders. You want it in only long enough for it to begin to turn clear down to the base of the shoulders. I use the 750 so the 700 may be a different composition but my tempilaq once dry will go from green, to clear, to black where it almost looks just like a sooty case mouth. My understanding is that the temp is achieved when the paint first starts to change phase and not once it has all burned off because once it has all burned off you have been at (and thus way past) the temp for too long.
I also position the neck shoulder junction in the middle of the annealing field. If the middle of the neck is in the middle with the shoulders further back out of the field it caused the neck to go clear way before the shoulders ever actually did signaling an uneven annealing job on the case. If I cooked it to where the shoulders turned the neck would have been at temp for 1 second longer than the tempilaq signaled it should have been. Moving the center point to the shoulder neck junction made it so both the shoulders and neck turned at the same time signaling an even job to me.
This is my annie and some 223 brass I tested on when I first got it, you can see the progression: 2 cases at each time interval, one with tempilaq and one without. 6 different intervals. On the left side was too little time in, on the right side was too much time. You can see that the tempilaq doesnt melt on those on the left and on the right it melts down too far past. What youre looking for is the point middle ground when the paint transition is just migrating off the shoulders like in the fourth pair from the left (right under the power switch). It has gone clear through the shoulders and is just starting to turn on the body.

Thats my understanding of it and the use of tempilaq in an induction setting. Your 700 may require migrating a bit further downward but if you can see the brass glowing you are likely getting too hot from my studies.
I just got some 450 in to test on the bodies and I should be annealing a batch of 50 after this weekend. Ill report back with a similar pic (provided I remember in a few days) but with the two different types used to see just how far down the cases the heat migrates. 1.6 seconds in the annealer turns the neck and shoulder tempilaq and I have to drop that bitch like its hot quick so Im sort of concerned about the downward heat transfer. Especially on my 300bo brass.
