Amazing advice for any new loader...I wish someone would have told me that.

As for loading 9mm...perhaps I'm just lucky, I really don't know. I've loaded Hornady offerings (like HAP and XTP), Missouri's Hi-Tek 9mm parabellum, and mostly 115g Berry's plated and not once have I had a single issue, ever. I've loaded them with all kinds of powder as well, Tightgroup, Acc N07, Sport Pistol, HP-38, W231, Bullseye...no issues with any of them.

I've also always loaded with used brass vs new. I've done all my 9mm loading on my Dillon 550 using their 9mm dies and again, no problems yet.
