Jmorris:
Your video is very impressive to say the least. I would think that now and then you would be forced to clear a mis-feed or mangled round. What problems do you run into with the 1050?
Almost none, it is rare that any problems occur while loading,that said, it is due to my process more than the 1050 machine itself (although the 1050 is the only manual progressive I feel is reliable enough to automate).
With bottle neck brass you cannot do everything that needs to be done in one pass on any machine, so they go through one pass to size/deprime and trim to length, generally with a "prep" tool head.
This is where you would find a mangled round, if it made it past a visual inspection before/after being tumbled.
Then they make a pass through an automated annealing machine so all of the brass is consistent on the loading pass.
It is not necessary for pistol to have a "prep" pass but I do it anyway if I am using an automated loader, as it is no extra work that has to be done by me and it is not uncommon for the machine to load 10,000 rounds without malfunction being fed processed brass.
This is how fast brass can be processed and again brass that will cause a malfunction will be found in this pass (before you are dealing with primers, powder or bullets).

If it match ammo it takes a trip through a roll sizer first.
Also helps to have everything sorted perfectly, I generally pass everything through this machine twice, first pass on its own, second I cull nested cases.
