You are welcome and I might add that to insure good results I run 8mm mag brass through a 7mm STW sizing die before trying to take it all at once from .323 to .257. That mid point at .284 saves a lot of brass. I have a ton of 8mm mag brass and no 8mm mag rifle anymore, except an 8mm Ultra Mag wildcat.
