The only reason I can see to screw dies down to the shell holder would be in the case of Redding Dies.
They instruct you (with the match dies at least) to screw them down to the shell holder.
On the flip side, I did that with an RCBS die once and got 30 casings into it before I noticed I'd just destroyed 30 cases. (Fortunately they were many times fired PPU...)
Next question:
At what point should you consider neck turning your brass, and why? </div></div>
Hardly a secret that I'm a devout Redding Slut and dig their bushing dies especially. Now it isn't like you'll be struck by lightning,if/when a die kisses a shellholder,but you are literally playing with fire if you go there by default and less some confirmation(s). I tell everyone the same thing,as a default setting with a new sizer,kiss the shellholder and come off it 2 complete revolutions,then tune in increments from there. You'll never get smoked and you'll not beat those "odds".
Same goes the seater. With a virgin hull in the shellholder and the ram raised,run the sizer down until it kisses the casemouth,then back off 2 revolutions and set the lock ring. This will preclude a crimp,irregardless of trim length and is a nice buffer,that is typically forgiving. It's an inordinate circumstance,in which that buffer won't allow any/all COAL's to whistle through a given chambering. If you come up shy,tread lightly and keep the buffer in mind. Unwanton/unknowing crimps will affect both pressure and precision and should be avoided at all costs.
"Neck turning" has become another catchphrase of sorts,misunderstood by many. The only time turning is a mandate,is when neck clearance is an issue and such is requisite to allow a round to chamber(a non SAAMI tightneck chamber). Don't get caught up in the mindset that doing so less that mandate,will "enhance" accuracy. That's bullshit and all you will do is increase slop in the neck of the chamber. Start with good brass,good dies,common sense,a clue,forget turd polishing and never make a move unless you've reason too. Kiss lands and rock on.
I'm a pretty big fan of necking down for an OEM chamber and flying a false shoulder in conjunction,to establish that warm/fuzzy headspace FEEL.
That's where the goody is found and reliably.
