Need Advice on Annealed Brass..(photo included)

[bubbaonpc]

I hope some of you might look at these. Salt Bath at 520 C. for 6 seconds.
Left to right shows starting shallow and working deeper...as you can see. I took some 3x fired 22-250 brass and experimented. I personally feel they were all too deep(#1 maybe not).. and got too hot, but this is my first try and I may be wrong. Your input will be appreciated !

bubbaonpc here is a photo of some Lapua 22-250 cases annealed in an AMP machine set to their recommended settings. Comparing the two photos I would say that your two middle cases are about the right depth IMO. Please be aware that different brass, even of the same make but different calibre can look completely different after annealing. I hope this helps and makes sense.

You cannot tell if brass is annealed correctly or incorrectly by looking at the change in color.

Can you go into more detail... I am hoping to learn all I can before loading em up...or trashing them. Thanks
