[QUOTE="westcliffe01, post: 896836, member: 35183"] This might seem quite a simple problem, but it is not. We are not sizing a brass cylinder of uniform diameter and wall thickness. The neck is attached to the shoulder of the cartridge on one side and nothing on the other side. Because of the different end fixing, the springback on each side is different. I personally find ball type expanders to produce a tapered neck. I prefer the lee collet neck sizers myself, but they are not always available for all cartridges. I do not have any chambers that require turned necks, but I can certainly see the benefit one can gain from keeping the neck thickness consistent and uniform. [/QUOTE]
