I'm in the same predicament. Glad to have found some info.

As an aside, I just sized 20 pieces of new Jameison brass tonight. When I went to trim it I found that the pilot of my new Forster trimmer was extremely tight. When I measured the inside diameter of the neck I got .471" and the Woodleigh bullets run .473". The trimmer pilot went into the cases, eventually, but it was a bunch of work to get it to work. Anyone else have issues with tight necks in sized brass? The dies are Redding so that shouldn't be the issue.
