300 Remington Ultra Mag Full Length Sizing Die

Your choice of reloading dies should not be a casual one. Your dies literally shape the quality and function of your reloads. Because they are so important, Redding gives them a lot of attention.

• We use the finest alloy steels obtainable.
• Our dies are machined on Hardinge Super-Precision® lathes capable of holding the tightest tolerances in the industry.
• We guarantee our dies 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 ultrasonically cleaned before packaging.
• The die box is a handy cartridge loading block and storage package. Inside is a spare decapping pin, hex wrench, and a place for your shellholder!
• All Redding dies use the industry standard 7/8-14 threaded bodies.
