This die slightly expands the case neck so that the bullet can be seated easily.

Technical Information

• Material: Steel
• Die Type: Expanding (or belling) die
• Accessories: Plastic storage case

Notes:

• Straight wall cases require an extra die to expand the case mouth
• The case mouth needs to be slightly flared to allow seating of the bullet
• This die is usually found as the second die in a set for straight walled cases
• Bottleneck cases get "expanded" as the case is drawn over the expander ball while being removed from the resizing die
