Hi!
I'm looking to get some info about the rcbs and noe expander unit. As far as i know, the rule to use these is the bullet diameter minus 0.003"-0.004" to get some tension on the boolit. While looking for customs expanders because rcbs does not have what i need in size, i read on the noe website that they recommend using their expander plug 0.001" larger thanthe bullet.
What would you do? I intend to shoot 0.316"-0.317" boolits. Do i need a custom 0.314" rcbs style expander or follow what noe recommend and get a 0.317" expander plug (i already have the lee die for it)? Am i missing something here?
