I have the RCBS Competition dies and an RCBS case neck sizer. With both of the sizing dies and handle all the way down, when then raising the handle to drop the case out of the die, there is a slight resistance. For the neck die, I use the Imperial wax on the outside. I don't care much for the graphite powder for the inside. There has to be some residue after sizing. I will be trying the One Shot for inside and outside tonight. Nothing ever got stuck, but I don't want to find out about it after the fact.
