Dillon Conversion Kit for 7mm PRC

[sdirks3]

Anyone have any experience with/advice on which Dillon caliber conversion kit to order for a 7mm PRC? I'd guess that the 7mm Rem Mag would be closest (same head diameter for shell plate, same caliber for powder die), but I'm also a reloading noob so I wouldn't be surprised if that's completely wrong

Adding notes here - looking up the shell holder sizing on the RCBS website, it looks like they say to use the same one for 7mm PRC and 7mm RUM, so maybe that would be a better choice for Dillon as well
