I use wet tumbler with ss pins. The inside of the the case mouth are too clean, 20 out 100 cases (range picked up brass mainly) would bind tightly with the Mr. bullet feeder powder funnel. When loading hand sorted brass with the same headstamp, this happens much less frequently. Btw, I am currently using XL750. I just placed an order for an RL1100 and I got a couple of questions:
1. Suppose I still use Mr. bullet feeder powder funnel for case flaring, would it be easier to break the bind?
2. Would a dedicated case flaring die (e.g. Lyman, or Mighty Armory) bind with the case? If not, I may just order one and put it to the swaging station on the RL1100.
