Re: RCBS 3 way cutter?
Yep I think it is worth buying a separate cutter head for each calibre. Last night I decided to set mine up for some Federal .308 brass I'd got kicking around, didn't take too long and the 3 way head did a great job - trimming exactly to length every time and a nice chamfer on the OD and ID. Just wish the cut on the inside was not at so steep an angle, sometimes it can still scratch the bullet (if neck tension is high from a FL size), although I suspect I just need to mess around more with the pilot depth to get the best cut.
