Re: Reloading new 7mmRM brass
Run it through the die so the expander ball trues up all the necks as some will be bent, etc. Some trim now or after the 1st firing. If there to long now, then you need to trim, if not you can get away with firing them this time, but probly end up doing it after the first firing. Next thing would be to chamfer and debur inside/outside of the neck and if you have it, flash hole debur tool is also nice.
Some weight sort but I find that a waste of time, JMO. My rifles with there preferred loads still shoot 1/2-3/4 MOA out to 800 yards with unsorted remchester brass.
Thats about all I do.
