My first question would be to find out what the case mouth diameter is on a loaded round - odds are you are a thousandth or two out of spec.
I shoot lead almost exclusively now, mostly because it's cheap. It's no dirtier or cleaner than copper, and it's actually easier on your equipment because lead is softer than copper and does not produce the same wear that copper jacketed bullets will over the same number of rounds.
Sounds like you have one or two little factors that are a hair out of spec for your particular rig more than anything.
