Question Regarding Redding Bullet Seating w/o Crimp
I've only ever reloaded 308 and 300WM; for both calibres I have only ever used Redding die sets. This 'problem' has bugged me for years. Grateful for any views / answers:
When it comes to bullet seating, I have always followed the requirement stated in the instructions regarding the need to back the seating die away from metal to metal contact with the shellholder in order not to crimp the case.
However, it has always struck me that hard shellholder-to-die contact would be a far more consistent means of stopping the press's upward movement of the shellholder.
...without shellholder-to-die contact the upward shellholder movement is only stopped by the press reaching its mechanical limit of movement. Obviously there is minute slack in all presses, and so vigorous hard press strokes produce bullets seated to a different depth to slow soft press strokes.
...and thus 'consistency' of press stroke is vital to consistent bullet seating depth.
...which requires concentration, slows things down (and is boring!).
(but obviously there's no problem if you seat with crimp!)
FINALLY (!) MY QUESTIONS:
Does, as I suspect, hard shellholder-to-die contact enable consistent bullet seating despite inconsistent press stroke speed/vigour?
Can the 'crimp' bit be easily polished out of the seating die to enable shellholder to die contact without crimping?
Is this a problem with all brands of seating die?
Thanks if you read this far!
