I used a RCBS trimmer for a long time, only thing I did not like how it was not aligned from the case head anchor
( shellplate ) to the cutter. The insides of the case mouths would have a little etching ring on one side from being forced to rub the pilot while trimming. I had modified it with a drill later in the years to make it faster and easier on the hands.
I would put that pilot in a drill and hone it down a little with some 220 sandpaper until it fits nicely in the case mouths.
I am pretty sure someone will say " Go Giraud."
