That's a old wildcat cartridge you don't hear that much about anymore.
If you are unsuccessful in your search for dies you might consider having that barrel chambered in 7 WSM.
Maybe RCBS or CH4D for the dies.

A Google search turned up two versions; rimless and rimmed. Is your rifle a single shot / lever action (rimmed case), or a bolt action (rimless case)? The case is similar to a Weatherby case in that the case wall / shoulder / neck transitions are radiused.

The cartridge designer / wildcatter was named Gradle IIRC, and he was in Santa Barbara. So the round has California roots. Good luck with your search!

Assume you've seen this?

Another forum had someone suggesting calling RCBS to see if they would custom machine the dies. Sounds plausible, but I wouldn't limit it to RCBS.

Good luck!

I would set the barrel back 2 turns and rechamber to 7wsm or 7rsaum.
That should clean out all of the old chamber, giving you a chamber for which you can easily get loaded ammo, brass and dies.
