Okay, got the Forster outside neck trimmer and .308 pilot.
The pilot measures .3055". I have RCBS and Hornady dies for 308 Win, 30-06, 300 Weatherby Mag, and the 7.62x40WT. None of the expander balls will allow entry of the Pilot. I even greased it, to no avail. I've got a Dillon 308 neck expander for my powder measure for my 550B, but the shaft is .300" and flairs at the top to flair case mouth, if desired. Doesn't expand the neck at all.
Also, the Forster cutter block strikes the lathe frame with the leading edge the entire length of the frame.
I could chuck the pilot in a drill and buff it down a little. I guess better to be to big than to small.
Have sent Forster an e-mail, but all in all, pretty disappointed.
All dressed up and nowhere to go.
