I need to know if there is a rimmed case that can be used to make a rimmed 25-06 that would use the standard dies with a rimmed shell holder

Looks like best option would be the 9.3x74; a little small (.005") in head diameter, but workable. The Mauser 57mm cases had rimmed versions, but would be too short for a 25-06, as far as I know the 9.3x62mm case didn't have a rimmed version.
You can get the 9.3x74 RWS cases from Huntington's

I found it in Ken Howell's book Designing and forming Custom cartridges. He states trim 400-350 NE brass to 2 1/2 inches. RCBS makes a form and trim die set to finish the job. Then fireform. It is called a 25-06 Rimmed. No other info is availible. It is identical to the 25-06 in every way but the rim. You could probably pick up a series of dies from gunshows 35 Wheelen 30-06 270 then finish it in 25-06 F/L die for alot cheaper than the form dies. A Bushing die to neck down in stages and 30-06 F/L to set the shoulder and finish it with the bushing dies would probably work. Also parent brass might be a PIA. hope it works out. If I knew how to use my scanner I would send it to you.
