All the company's now days are using 7/8''x14 thread dies and press's. The only place you MIGHT get into trouble, is with a progressive press. I've talked with a few reloaders at some gun shows, where the full lenght sizing die,from one company wasn't long enough to thread thru the head of another press, and actually size the entire lenght of the case. In these instance's, it was reloaders using Lee Dies in a Dillion press. From what I was told, when you raise the shell plate on a Dillion, to TDC, the Lee full lenght sizing die, with the lock nut adjusted all the way up, doesn't touch the shell plate. I've got no problem using Redding dies in my Dillion, or Hornady. gypsyman
