RCBS lock out die set up

[Roland Thunder]

I recently bought a RCBS lock out die for my Dillon 650. I have a question about the set up. I understand how to adjust the plunger into the die body but how far down do you screw the die into the tool head

The instructions that come with it say to thread it in until the bottom of the die is about 1/4" from the raised shell plate. That works for me.
