Another thing I did was to firmly push all the ends onto the primer feed tubes. Those green and clear ends. I found that it stopped primers from turning around. I have 18 large primer pickup tubes and I put them up against the wood post in my basement and pushed the ends on another 1/8 of an inch, end of turned over primers. 1 XL650 just for 45ACP and another XL650 for 9mm. Did the same with the 10 small primer pick up tubes.
