[QUOTE="cdherman, post: 1277382, member: 12282"] [b]Re: Neck turning, before or after fireforming, before transitioning to bushing neck sizing for[/b] Forster actually says only neck sizing is needed before turning. I would think that it is important to size the neck ALL the way to the shoulder in a fired case -- otherwise, the outside turner would cut more brass off, over the unsized area of the neck and make it weak. I assume that you feel a full length resizing will leave the neck more concentric and centered to the body of the cartridge? I don't quite follow that a FL resize is needed. So long as the inside diameter of the entire neck has been determined by a mandrel or expander ball, why would it not be OK? Obviously, when you outside turn brass, the variation in wall thickness needs to be on the outside. The forster turner pilot is about an inch long and forces the entire neck of the cartridge into a fixed rotation while turning. I'd rather not work my brass with a step that is not definitely needed. Once I'm fireformed to the 280 AI, I intend to size the body only if I'm having feeding issues, and even then, I will bump the shoulder only 1-2 thousands..... [/QUOTE]
