Forster Full Length Sizer Die 300 RUM (Remington Ultra Magnum)

Use after each firing or after several firings, when the resulting brass flow will require the case to be full-length sized. Allows case to be re-chambered in any SAAMI rifle chamber with minimal play.

Features

• Sizes the case neck, shoulder and body and expands the neck and removes the spent primer.
• Precisely-positioned vent hole located in the threaded or recessed portion of the die body prevents excessive, trapped air and/or lubrications from damaging the die’s components or your cases.

Note: For use on military brass with crimped primers, use a decapping die first to remove spent primer (not available from Forster Products).
