I think Ken Light had very good and detailed instructions with his annealer. I don't have a copy but there may be some online or one may be able to call him for a copy. I'm not an annealing expert but I did study it before I started annealing and his instructions were supported in everything I found on the subject. Per this info, yes, I'd say they do "look" over annealed, IMHO. Apparently, the Lapua "ring" is in part due to time, that it becomes more apparent while on the shelf. I've seen this with brass that I annealed approximately a year previously. His instructions are a few pages long and I believe they address this as well as using vice grips to test it. I don't think of that as the most quauntifiable method, but after you see and do it a bit, it's pretty good, IMO. I think his instructions are a good basis for anyone wanting to anneal cases, to follow but I won't go as far as to say what others do is wrong if it works for them. YMMV.
