I just bought the full Wilson trimmer kit from Sinclair, but I haven't had a chance to use it yet. Will try to remember to come back here and let you know how it goes. Was previously using the Lee zip trim, which is really very fast, and a great value for the price. Problem I had was that the little rods that control the trim length were wearing out on the ends -- getting gradually shorter, and trimming my brass too short. I wanted to be able to control the length myself, hence the new trimmer setup.
