Tapered Expander Plugs

Primarily used in case forming operations. Tapered expander plugs provide a gradual taper that is useful during "necking up" operations. They have a transition slope of 1 inch. That means that the distance from the start caliber dimension to the end caliber dimension is 1 inch.

Tapered expander plugs are grouped by calibers starting with beginning caliber and tapering up to the finish caliber.
