I've used the Hornady cutter, the RCBS press mounted swager, and the Dillon swager. The Hornady is the fastest but chamfers the pocket more than required. The Dillon works fine but doesn't provide any chamfer at all to the pocket. The RCBS is junk and not worth the time involved. Presently I use the Dillon and follow with a slight chamfer from a deburring tool.
