A few months back I annealed a 30-06 case. Heated and quenched. Went straight the full length sizing die and the neck crushed down into the shoulder. Case was cool enough that it never left my hand. I figured I had just over-softened the solder. Last night I did almost the same thing only this time I used my Lee neck sizing die. The neck gaul to the to the sizing rod and pulled it off the shoulder, separated the the neck at the solder. I think I need to let them cool a little longer next time.
