When I set up for reloading again last year, I dug out my Load-Master for the progressive. When I'd last reloaded, I was ready to throw it out the window--
So I started from ground zero: I did a detail strip and clean, and even sent it to Lee for an initial setup. Then I followed up with changing out my die setups to five-die configurations, and I reviewed the (then-new-to-me) YouTube videos, and followed their advice.
It now functions fine--but primer changeouts can introduce erratic priming if the trough and anvil assembly is not clean and, IMO, lubed with a touch with powdered graphite.
Overall, I am satisfied--but if I could afford it right now, I would look awfully hard at the Hornady LnL.
