Just to wrap this up. I gave the 200 cases a quick dunk in acetone to remove the lanolin from inside the necks. It's stuff that's too dirty for creakote prep that I hate to throw out. This is not a long term solution but allowed me to move on with this batch.
I annealed a handful more and tried a mix of alcohol and 400 mesh (fine powder) graphite in the necks before mandrel sizing. This worked just as good as the lanolin/alcohol mix I use for FL sizing and will save the step of having to clean the inside of the necks to keep powder from sticking.
Eventually I'll get a carbide sizing mandrel
