Hi all you annealers out there
I have a bit of a interesting issue after I anneal my 223 cases.
Annealing works great and the tempilaq shows the great temperature I am looking for.
The issue I get is that after I have done the anneal of the cases I neck size with my wilson die.
Fist couple of cases work fine with a slightly more tight feel but all ok
Then the necks start to get small scratches in the case and I can see scratched in the bush.
Tested on two different cases lots and both give the same result. I have ordered a redding titanium nitride bush and see if I get the same results.
Has anyone seen similar problems.
A really curly one.

Because you have softened the necks they will pick up more easily on the sizing die - just like a new Lapua case will do on an expander button if you use one before the first firing. Even carbide buttons will pick up. Once you get the first bit of brass picking up on the die the problem will get worse, you need to clean the die or bush to get the brass off to stop it happening. Steel wool will do the job. Lubing the cases prior to sizing will also stop the problem providing there is no brass build-up on the die/ bush. You will then have to clean the cases again after sizing which is a pain.

Hi Malcolm,
Great points that make a lot of sense.
I do use lube after I finish the anneal but it is the graphite stuff in with the balls.
I might have to head back to the imperial lube and see if that helps.
I will try steel wool on the cases and lube with imperial once I get my new bush. I hope this solves the scratches and damaging the bush

You will not have damaged the bush, it will just have a build up of brass on it. That is what I use the steel wool to remove. The bushes are hardened and the brass won't damage them but it can and will build up on them causing them to look and feel rough. Once the necks harden a bit from firing they don't pick up as easily or scratch from the brass deposited inside your bushes.
