+1, when I started lubing cases, including 9mm, it made a HUGE difference. The sh*t used to fall off my bench that's how much stress was there before. Now I barely have to make an effort. An occasional, slightly more bulging than usual, 'glocked brass' would still require some effort, but nothing compared to just clean cases.
A squirt of Ballistol into a Ziplock bag then tumbling about 100 cases for 30sec is all it takes. Then rolling it in a towel for another 30sec after its been loaded. No tumbling.
