Expander Plug

In FLR a shell the expander ball meets resistance when it leaves the neck portion of shell. Aside from dipping the neck of shell in graphite or putting a high polish on expander ball- anyone have a better idea???

What’s wrong with graphite?

I actually dip the neck in graphite an then size it with a pma carbide mandrel. It creates the best conditions for bullet release.
