I rarely load a cartridge from start to finish.
What I do is have at least 100 brass for each caliber.
New brass primer pockets uniformed, trimmed for length necks skim turned, weigh sort into two batches and mark them, eliminate the outliers. New brass is fireformed to the chamber, I do this to reduce , if not eliminate, the first firing stretch, which could be up to 0.008".
On a fired piece of brass; #1 clean neck and shoulder area with 000 steel wool, anneal with torch rotating brass in a drill motor, in the flame 8 seconds, do all calibers at the same time.
#2 run brass through a Redding body die (set this die up with as close to zero set back as possible, like 0.001") dwell time ~ 5 seconds
#3 Brush case mouth with a nylon bore brush , just in and out, now run bumped brass through a Lee Collet die with ~5 seconds dwell time.
#4 Before priming , this is with a new case and only done once, uniform the primer pockets to take the radius out of the bottom of the pocket, The primer will seat firmly and I do not clean carbon out of the pocket as there is no discernable build up.
#5 Charging cases, use an FX 120i , Lee dippers, and a powder trickler. This is the slowest part of the operation, but one that demands precision.
With the Lee collet die there will be a requirement to neck turn after several cycles as a 'donut' will build up at the shoulder / neck juncture. Skim turn at the mouth and remove material along the neck to the shoulder.
For trimming cases I use the Lee system (case length gauge and trimmer) chucked in a drill motor with a Lee universal shell holder.
In the life of the brass this may only be a few to 3 times, as my dies are set up minimum.
Once set up, the monkey motions to do this are all mindless except for powder dispensing.
These steps are always on going but only do 1 or 2 at a time with powder dispensing a stand alone.
I get generally good results doing it this way.
