After trimming a bunch of 30-06 cases to length today, using the Lee trimmer in a power drill, I chamfered and deburred. I was careful not to create a "knife" edge but when it came time to seat a bullet I noticed that some of them were a little stiffer to seat than the others. Upon closer inspection I notice flakes of the copper jacket on and around the case mouth. Did I cut to sharp and edge on the mouth or not enough? What did I do wrong? This didn't happen to the brass that didn't need trimming.
