I do not have a fancy set-up for trimming the cases. Miine are done the old fashioned way, CNC Bridgeport. ;) In a pair of alunimum jaws about ten inches long, I bore holes to fit the lower portion of the case. Insert the cases and press the pendant and off it goes. This set-up allows very close OALs to be kept over many hundreds of cases. The endmill cuts them very square and with not much of a burr.
After that, I size them and they are ready to go. Years ago I bought thousands of once fired military cases from Bushmaster. I know it is cheating, but I just did not relish the thought of doing these by hand. :D
