Very, very cool.
You have a genuine factory going there.
It's a belt driven eccentric running the whole works.
It's dropping cases in the bin as a demonstration?
Very clever.
It's just sizing/depriming and swaging the brass in that video. Processing the brass this way ensures that there are no snags once you have the powder measure, powder check die and bullets in the collator.
Good stuff. I didn't notice a return spring on the powder bar? The hesitation of the powder bar caught my eye. Without a spring the powder measure failsafe linkage must be doing the job? Again, nice setup.
I'm not sure when Dillon quit putting the springs on the powder measures. Likely about the same time they came out with the fail safe linkage. Many years, that's for sure. My last 5 Dillons have not had them.
