Last night I was testing my annealeez on some 100x old WIN 1F 308 I had lying around.
I used their instructions which mentioned that as soon as flame changed colour it was annealed, also tried it in the dark, case neck had a slight dark red glow.

I am now comparing my WIN 1F with some Lapua 0F I got.
On my WIN the case discoloration is just very slightly under the shoulders.
On the 0F Lapua, discoloration goes a good 1/4''+ lower than my WIN casings.

Is this even an indication?
Tried finding some 650 or 750 tempilaq to no avail.
 
That what I was thinking, just looking at my lapua brass got me confused for a second.

Some guys say as soon as orange flame appears you're good to go, so others seem to say if ever any orange appears it's overcooked.
Even if I had tempilaq at hand, reloading manuals do not cover much on annealing.

No, it isn't. The number one factor in development of heat tint is how clean the surface of the brass was before it was annealed, a factor that is of little or no relevance to annealing.

I have seen quite a few people make this statement, I am very skeptical of it. Have you seen any sources for this that appear credible?
 
Thanks to a member who sent me a PM found some 650 tempilaq.
Will apply under shoulders and if it melts i'll know I gotta remove at that moment.
I can then see how my brass looks like properly annealed.

I may be conservative but want the brass to move out of the flame just as the 650 flashes off.... both events happen at the same time. Some tweaking is needed depending on the brass alloy and how hard it has become before annealing but this reduces the chance of going too far. I will adjust flame and time to suit that batch of brass I am annealing.

Remember that the difference between just right and too much is a few tenths of a second.

The coloration on the case is NOT a good indicator. Just start testing brass made from other manfs and you will see..... even different lots of the same brand can show some different coloration.

good luck
