I am seeing issues with range pick up brass too. I use Lee dies because I found them to normally solve pick up brass issues. However, I am having one out of four 45ACP loads not passing my go/no-go gauge. Never had an issue with 45 loads before. Starting some searching and seeing posts about more people seeing these issues - speculation is that newer brass is "thinner" to save costs. Anyway, I ordered a LEE 45ACP undersized die that is due tomorrow - hope that will solve my 45ACP problems.
Currently not having issues with 9mm but I load 124 Bayous. I wonder if your issue would go away if you were loading 115s or 124s? I did have issues with loading Bayou 135s when I ran into the 9mm cases with the "step" - the 135s hit that step and the loaded round was too fat to chamber.
