A Giraud trimmer is in the same class of essential tool for me. It's crazy fast. It trims to length and de burrs inside and outside in a single 3 second operation. I'd quit reloading if I had to trim and deburr the old way again. It's so fast I use it on every loading just to get a nice chamfer on the ID and OD. I did 200 pieces of .260 brass the other day in ten minutes.
