Check the Dillon board or gugle it. They didn't have a shell plate for it so one had to modify one of the existing shell plates for it. After that, I think the indexer block had to be shortened and dies couldn't protrude much below the toolhead - it would index before the case was clear IIR all that correctly. I know one guy using an XL650 for .338 LM but I've not seen exactly how he's doing it. I may get a chance to check it out soon and will report back. I think he told me he removed/disabled the auto index feature to do it but, again, I've not seen it or talked in detail with him. He may not be running it as a progressive at all. He is shooting some impressive groups at the range though.
