What's the big difference between full sizing and neck sizing? I mean, except the obvious, how much more time does one take than the other, and how big of a difference does it make? Any special tools?
Well, you got two different dies. One that only sizes neck, and one that sizes neck, shoulders and body. Thats about it. You don't have to lube neck sized brass. Which is a time saver. You have to only shoot neck sized brass in the gun fireformed in. Drawback. Also neck sizing alot can knock neck runout (concentricity) out. Only tools are the dies.
The way DM does it is really best. Neck size, fireform, and then you got a piece of brass to work with.
