We loaded our first batch of 9mm last night in our Dillon RL5550B. After getting the dies all set things went pretty smooth and I am really liking this machine so far. I have two questions, first is the cases have a little hour glass shape to them, not much but you can see it. Both of the ends of the case are within spec as is oal but the center is approx .015 smaller. What causes this and is it ok? The second is when pulling the shell out of the powder funnel sometimes the powder spills out of the funnel and not into the shell. This is intermitent and makes a nice mess when it does it. Do you have any suggestions on this?
