why do we have to claim the creed isnt what it is, its not a necked up nothing blown out nothing it is a 30TC case, necked down, period thats what it is, i can make creed cases out of 243, doesnt make it its parent case. i think some of you like to argue for the sake of arguing. the .30 tc was developed by thompson center arms, it has no parent case. just cause all short action calibers have the same head diameter, doesnt mean they were all developed off a 250 or 300 savage
