Redding Neck Sizer Dies only size the neck of your bottleneck cases to prolong brass life and improve accuracy. It is important to note that since these dies size only the neck and not the shoulder or body, fired cases should not be interchanged between rifles of the same caliber.
The neck (NK) resizing die contains a decapping rod assembly with a neck expander (size button).
Made in the USA. Redding dies are made with the finest alloy steels obtainable. The dies are machined on Hardinge Super-Precision lathes capable of holding the tightest tolerances in the industry. All Redding Dies are guaranteed to produce ammunition that will properly fit any standard (SAAMI) chamber, regardless of action type. To maintain tolerances and guarantee that your dies will last a lifetime, they are heat treated in atmospherically controlled furnaces. All dies are hand polished for smooth, flawless functioning, inspected, and are ultra sonically cleaned before packaging.
