The clunking that i think you are referring to is a function of no case lube in the case mouth. I lube in a half cardboard box with 1.5" sides - holds about 1,000 cases at a time. couple of sprays across all the cases, jiggle em around do another spray across all the cases. Then I jiggle the box to stand up the cases and get about 80% of them stood up. spray the lube across them. you can repeat the last step if you want but the idea is that the loading operation is butter - nothing sticks or clunks coming off the powder die as this can lead to other issues. The entire lube operation takes 20 seconds/1,000 rounds.
