Description

Our mandrels are longer than other expanding mandrels and feature a special dual taper which expands both on the up and down stroke of the press to more uniformly expand and straighten case necks.

Nice tool
This expander works great in my Sinclair expander die. Great machining and finish. I'll definitely be getting other sizes for different calibers

.243 expander
Excellent product as always. I did very lightly polish the mandrel without dimensional changes and viola! The customer service rep at PMA was very helpful and on the ball. Definitely my go to provider for specialty items.
