I try anealing some brass and it would get the blue line at 6 or 7 seconds. Then I did my lapua brass and it took 7 or 8 secconds but it would get a yellow or orange looking ring. I did oone lapua longer and if I did it for 9 seconds it turned red so I know I didnt under do it. here is a pic I'll post better ones in alittle bit.
