458 Socom case dimensions have changed since introduction. Early dies were a little undersized, making it difficult or impossible to resize cases without having them stick in the die. If you think you might have one of these dies, please return the die to the factory for replacement. Please include a couple of fired, unsized cases so we can test the replacement die on brass fired in your rifle to ensure proper function.
