Let's just assume there isn't any neck or shoulder to deal with. For arguments sake lets just call this a straight walled pistol casing. I have a drill press available but no lathe. Is this as simple as just finding the appropriate 3c/5c collet that I can chuck in my drill press then using a file just hold it on the casing rim as it spins?

I'm guessing you would do this a little at a time, stop, measure, then do it again until you remove the appropriate amount of material? If I making this harder than I should or am trying to make it simpler than it is please chime in. This is a first for me. I don't have machining experience. Even a 3c collet would be a new one on me.

p.s. Let me clarify...I'm thinking about a collet that would fit inside the casing to hold it...not outside.
