[QUOTE="Dragoon300, post: 2720237, member: 115285"] Mandrel ID neck sizing is best for all the reasons mentioned above. Also, case deformation in the shoulder resulting in runout happens when pulling an expander ball out through the neck, especially when not properly lubricated. The neck / shoulder better resists the forces of mandrel expanding into the neck. Neck turning is a good thing to do when done correctly, but is not particularly necessary when mandrel sizing for a normal chamber. However, on a tighter chamber (in the neck area) neck turning is necessary. But even with all of this, consistent neck tension is difficult to obtain with different hardnesses in the brass being used producing different amounts of spring back, and tension. Anealing is the next step the neck tension quest. It is very frustrating when you are not able to obtain consistent neck ID'S due to varying spring back. [/QUOTE]
