I think that Redding will make dies for it;far as I know the first two sets of 7mm Mashburn Super dies they made were for my friend and myself,made with cases fired in our rifles, so they are willing to start a project from scratch.
Of course I think RCBS will do them as well, I bet.The form/trim,and FL dies for the Mashburn are standard catalog items with them.The Rogue is not too much different so shouldn't be a problem.
BTW there something wrong with Hornady dies? I have never owned them.
