Husky, you maybe right, my experience is lack of annealing show up in cracks in the necks at firing, different neck tension in batches resulting in poor groups and stiffness / stickiness of the case during FL sizing when your trying to get the expander ball / mandrel our of the neck on the upstroke. The deformations here i think is more from having lube or oil, cotton etc in the chamber at firing but again hard to tell without seeing / knowing the whole picture.
