Reloading Dies

Please read before using your sizer die

Whidden Gunworks reloading dies are the best way to be sure you are getting the most out of your time at the reloading bench. If you want maximum precision for your favorite rounds – including many wildcat rounds – you need the tools we build into each one. Both the Whidden Bushing Die and Whidden Standard Die are manufactured to tolerances that exceed most expectations.

Bushing Die

The Whidden Bushing Sizer allows the flexibility of neck tension should a different thickness in the neck of the brass occur from one manufacturer to another. The bushings also allow the shooter the opportunity to achieve the desired neck tension after neck turning of the brass. The bushings allow for .001” increments in neck tension in a range from .20 to .375 calibers.

Sizing Die

Whidden Gunworks manufactures custom dies for you to match your exact specifications for .20 Caliber and larger. See our custom dies product page for further information. 

NOTICE: We keep all standard caliber reloading dies in stock. If for some unforeseen reason we are out of stock of a caliber die, you the customer, will be notified within 24 business hours of the order being placed.
