I hear ya!!! I just got done with 308 pieces of 30-06 brass! I did it over a two week period, that included the tumbling & sizing. I have a manually operated RCBS trimmer. I find the chamfering / deburring chore to as tedious as the trimming!
ya thats the same tool I use, thinking about one of those 3way cutting heads that chamfers and deburres while trimming that might take the curse out of it
