You really need to get a Sinclair Manual (& catalog!) for a really detailed explanation.
In passing, I'll say that outside turning is the best way. Inside reaming will follow the hole, so if one wall's thinner to start with, it will be thinner at the end. Outside turning will uniform the case necks. Don't try for a 100% clean-up, 60-75% works fine on factory chambers.
K&M )I think) has a new tool to remove the donut, but you can get it out by using a neck expander - moving the donut to the outside - and neck turning.
Hope this helped, but I really recommend reading some advanced reloading books to get all the data you need!
