Anyone ever try to make a profile ground end mill to trim and chamfer in one step with a WFT or similar? Basically just grind a tool with a “W” profile that would do all three cuts in one. You would grind it based on your case neck thickness and your neck tension. As the case neck wears down the inner chamfer will remain correct as it’s set by neck tension dimension where as the outer chamfer will shallow-up as the neck thins, but who cares.
