For your reference "Here is a link to an article about annealing."
Here are a couple of pics of factory 338 Lapua cases that show the factory annealing.
I've always done it by hand but since I've got a few hundred to do I now have an automatic annealer made by Ken Light. Problem is I can't use my hands much for the next month or two so it'll be a while before I get it up and running.
Looks like your fourth from the left is pretty close to the factory job. The case on the right looks like the neck got too much heat and possibly a too far down on the body.
