Which of the following should not be done with a carbide die?

When using a carbide die, it is important to understand the specific purpose and limitations of the die material. Carbide dies are known for their hardness and durability, making them excellent for resizing operations and decapping cases. These dies can withstand the pressures of resizing without wear.

The process of cam-over refers to the mechanical action in which the press is designed to continue moving slightly after the die contacts the case. While this technique is often applied with steel dies to ensure consistent pressure, it's not suitable for carbide dies due to their brittleness. Excessive cam-over can induce stress and potentially crack or break the carbide material. Therefore, while decapping, resizing, and trimming are processes that can be appropriately performed with carbide dies, employing a cam-over technique is advisable to avoid damaging the die.
