Ok so to start with understand your only as efficient as the material you use.
1. Us only federal or Winchester primmers
(Cci and Remington suck)
2. Ball powders only! No flake no stick
(Powder should flow like water, I have not seen a measure for automated loading that handled the task reliably)
3. Clean brass means clean press
(Dry tumble brass as carbon from firing will not allow brass to stick in carbide dies)
(Wet tumble only after brass is processed and ready to load) you will hate life if you don't
4. Actually clean and lubricate the press monthly
(This means you understand the press and the operations performed)
5. Have enough primmer tubes to hold 1000 primers.
I would recommend a dillon 750 and casefeeder
Just a different perspective. During a shortage reducing what you allow yourself to use may leave you not shooting instead of working up a load for a new combination of sourced materials.
#1 i have loaded with 10's of thousands of cci primers to no ill effect. Remington primers are labeled differently but I've used them with 100% success as well.
#2 I'm a handgun reloader. I've had great success with bullseye, power pistol, h110 unique, sport pistol, titegroup, WST, 231, trail boss. That is my current range of powders and as the shortage eases I'll be adding BE86. All through a dillon powder drop and a powder check on the 750. The worst variance i get is 2 tenths of a grain on unique. It has caused me no issue and my accuracy is spot on. 9mm,380,44mag,45acp.
#3 i only wet tumble. Pins, dawn, lemishine, hot water. Dry in a dehydrator. All my pistol loading i use a spritz of hornady one shot and the press runs smooth as can be.... unless it's sellier and bellot... then it's two or three spritz of case lube. Love life.
#4 as needed. Agree more in the beginning as you learn what needs what. Mine gets a full detail after about 7000 rounds or at caliber swap, whichever comes first.
#5 agree.. I've only got enough for 800 at the moment but it would be nice to have more. Not an issue these days as primers have become problematic to get regularly.
