This priming system appears to be nothing but the Pro1000, but with a feeder. On the Pro1000 the primer tray rubs on the tiebar which has notches on it. The purpose is to shake the primer tray to keep primers feeding. Why the guy in the video has it running into some kind of die, I have no idea. I wouldn't do that.
I like the Pro1000, and I never found it to have that much for problems. My question though is if the Pro1000 priming system wasn't good enough, in what way is this 6 pack an improvement? I don't see one iota of difference in that primer chute. The only difference is my Pro1000 took the old round tray, where now they use the new flip style tray. I guess the only real advantage I see is that now everything is out in the open. You can see what all is going on, where the Pro1000 went under the shell plate.
