I use a Dillon 650. For pistol cases, first, I wash in warm water and liquid tide in my rotary tumbler. Then I fill the hoppers and load. all done!
For bottleneck rifle cases, I have a toolhead dedicated to an RCBS decappng die. I decap, wash and dry, spray lube with Dillon spray, ***(Not Hornady one-shot! I've stuck cases in the die with that stuff!)*** load normally, then tumble in corncobs and mineral spirits to remove the lube.
