...well there is a "problem" for a lot of people who like the concept of a 10mm revolver but don't want the hassle of dealing with the clips...

Was on another forum and one of the posters there knows of someone who has already made the request for 10K 10mm rimmed cases...so if a buch more of us ask it can happen...

As far as a shell holder goes...I would imagine Dillon would come out with one once the brass becomes available..and the rest would follow.
