Dingelfutz, is dead on and that's the exact passage I was thinking of but couldn't recall at the time. But Ive tried it and saw some results of a tightening and spreading of the loads, but only slightly. However I was using limited components and limited time. Additional testing could have produced better results. That particular 12 gauge Pedersoli I was using may have been slightly or very particular on the combination or configuration of the powder/shot wadding I was using. I may get back to it sometime.
