using cerosafe on dies?

do you think i can use cerosafe to make a casting of the inside of my form die and full length sizing die? Have any of you done this before?

Sure, why not?  I'd make sure none of the Cerrosafe would/could enter the thread sections on top
 If something get's screwed up, just boil the die in hot water.
 

Have any of you done this before?

No, and I can't fathom the need to. I just measure the brass after it's sized.

this is a wildcat. i do not have the rifle for this. i think the brass needs to be fireformed to final shape. i would like to cast the sizing die and compare to the un fired brass to see if i am right. would like to someday have a barrel chambered to this, but still trying to positively identify this thing. running the brass in the form die and then the sizer still leaves rounded shoulders. i think the shoulders are not yet touching the sizing die.
