Re: Quick question about loading 223 on a progressive.
I've found that running .223 brass through my 650 Dillon press works best. First pass is to deprime, size, and trim using a Lee universal depriming die in Sta #1 and a Rapid Trim on Sta #4
All cases get sprayed with a little Dillon Case Lube while in a gallon sized zip lock bag. Tumble around then pour out to let dry in a cooking pan (don't tell my wife I have it). I then load them into the case feeder and the dried lube isn't an issue.
The cases are then inspected for primer pockets that need crimping or any neck splits. Even the splits that are hard to spot because they're just small cracks show up real good after being trimmed.
When ready to load, I change tool heads and Station #1 has a Lee Collet Die that I've modified the point of the depriming pin for easier entrance into the sized case.
Since I usually have between 6k - 8k cases prepped and boxed, ready to reload, this system works best for me. When I get back from shooting, all fired brass goes into a 5 gal pail, mine and anything else I might pick up, to wait for another "Prep Day".
