1) FL sizing dies with regards to the neck. They size smaller than needed and then the expander ball opens it up on the way out. Could you take out expander ball, FL size and then open up using say a Sinclair expander mandrel? I realize this is slower, BUT if time wasn't an issue is this an a good way to FL size brass?
2) Lee collet neck sizing die. The mandrel is set to a specific ID and the brass is squeezed into the mandrel by the collets. For 260 Rem, what is that ID? I know you can call Lee up and get different mandrels, what would be a good ID for .002 neck tension out of a bolt gun.
