Hi
Fairly new to reloading, so assume I know nothing lol.
Reloading for a 6mm Dasher, and the dies I have other than the seating die are:
- Forster FL die (with expander ball)
- Redding neck size die with bushing
I have been told that the Forster FL die is over working the brass because it first contracts the neck and then expands it using the expander ball. It does have the removable expander ball. Is there a point in me getting a Redding FL sizing die with bushing? The idea is that I can remove the bushing and just do the shoulder with nothing to the neck, or if I need to size the neck, I can pop the bushing back in. OR, can I just remove the expander ball from the FL die and just do the shoulder + neck contract?
I do have a few questions regarding if and when I should be sizing the neck.
1. If my twice fired brass chambers without an issue, I am guessing that I don't need to bump the shoulders for any reason. Does this mean that I can just use my redding to size the neck and then seat the projectile? If I am not bumping the shoulder, do I even need to size the neck or can I just go straight to seating? (I am thinking not, as the neck might not adequately hold the projectile).
2. Is it recommended to get the mandrel die to expand the neck? If so, what would the steps look like? Will I be sizing the neck with the redding die (assuming I don't need to bump the shoulder), and then use the mandrel to expand? If I do need the bump the shoulder, my current Forster die also sizes the neck. Will the mandrel die be useful in this scenario?
Basically it comes down to if I should be getting the Redding FL die with bushing and/or mandrel die for neck expansion?
Thank you
