Unfortunately they would not. Customer support on the phone stated that the modified die set is only sold as part of the $200 caliber conversion kit, no matter that I don't need anything out of the kit other than the dies. Since I have not used the dies I ordered yet, they set up an RMA and will ship me a modified size die only in exchange, refunding me the difference. I was instructed to see if my .308 seating and crimping dies are short enough to allow the case to pass, and if not I need to remove as much as 1/4" or more from each die body. Frankly, I don't have the tools or know-how to do something like that. Kind of annoyed with the whole process.
