I too have had this problem with Starline. They pretend to be the reloaders friend, but ignore us when we ask for information. I have no trouble making 25-20's out of new 32-20 cases. It would be a cinch for Starline to manufacture 25-20 cases, but they won't listen to us. I see that they have added some really common cases to their list, but I will never be a customer of theirs again.
