Just an update ...
This evening, I nervously tried my first genuine production run with the Pro 2000, loading 50 rounds of 300 Blackout.
I had a bit of trouble at first. Somehow, another loose primer found its way into the strip feed mechanism, but once I blew the loose primer out, the mechanism worked fine.
And once I developed a process -- bullet, case, lever down, lever in -- and a matching rhythm, all was well.
I ended up with 49 good looking rounds. One, however, got the primer in sideways. I'm still trying to figure that one out.
Still, I'm calling it a success
Thanks to GWS and all of you for your help!
Enjoy!
