I just recently began annealing my brass and am wondering if I am doing something wrong because I am not getting that nice blueish color on my brass that you commonly see on new Lapua brass. In fact, my brass really doesn't change color at all. I am using a timed induction heater to heat the brass (not an AMP, but the DIY version), and have applied the green tempilaq (750 degrees) right where the shoulder meets the body of the case. I heat the brass until the tempilaq begins turning black, so in theory it should be reliably heating the neck and shoulders to 750. But there is no color change on the brass, which has me second guessing myself. Maybe this is because my induction heater doesn't use an open flame? I'm using hornady brass and Barnes brand brass so far. Is the color change in the brass irrelevant as long as the tempilaq is turning the right color?
