I am not familiar with the Lee Collet Die, better look into it.
Do a search for Mathman's instructions on that die and how to use it.
Much better than what Lee recommends.

In addition to Mathman, Woods was another user who offered a lot of useful info on these dies if you run across his name in any of your searches. Both of these guys are who got me turned onto the collet sizers (and how to best utilize them) several years back.
