My old rcbs case trimmer 2 is getting worn out and cutter is very dull. I know you can order new cutters but with the collet system for holding brass it takes a while to trim a large amount of brass! I am thinking about getting a new system. I have an old Wilson that I have never used but before ordering alot of the shell holders for the Wilson I also one of the wft trimmers for 22-250 and it is ok but I would like something more on the precession side. So I thought I would ask what is the preferred set up?
