Description

SAC MODULAR MANDREL SIZING DIEThe Modular Sizing Die has a unique design where the cartridges body geometry is sized by the die body, the cartridges shoulder and neck geometry are sized by a Neck Shoulder Bushing. This allows one die body to be used for the whole cartridge family. Furthermore, the Modular Sizing Dies are precision machined with the main focus of properly sizing your fired brass. Our resizing dies will size the base of the cartridge slightly more than the shoulder.

“The Modular Sizing Die” has a unique design where the cartridge’s body geometry is sized by the die body, the cartridge’s shoulder and neck geometry are sized by a “Neck / Shoulder Bushing”. This allows one die body to be used for the whole cartridge family.

Furthermore, the Modular Sizing Dies are precision machined with the main focus of properly sizing your fired brass. Our resizing dies will size the base of the cartridge slightly more than the shoulder.

After studying precision CNC machines and tooling, we designed the Modular Sizing Die to utilize a series of shallow tapers, not threads to properly center and secure the Solid Decapping Pin. Our tapered geometry offers unparalleled concentricity and repeatability.

Last but not least, we designed the cartridge sizing geometry to size a little more at the base and a little less at the shoulder when compared to most resizing dies on the market. In properly sized rifle chambers, this helps eliminate extraction issues of fired brass. Our shoulder sizing geometry and helps minimize case runout and over working of the brass by not sizing the shoulder too much.

MODULAR SIZING DIE ASSEMBLY
  • Modular Sizing Die Body: Standard 7/8 x 14 threads, 17-4 Stainless Steel, Special Salt Bath Nitride finish for increased lubricity and performance compared to other resizing dies on the market.
  • Solid Decapping pin: Designed to be slightly smaller than bullet diameter, the Solid Decapping Pin WILL NOT expand sized necks, however, will fix dented necks, increasing neck uniformity. Utilizing a .058” nominal diameter pin tip to fit in small primer flash-holes. The Solid Decapping Pin can be set to any pin tip protrusion or by simply adjusting the wide mouth retaining clips position.
  • Knurled ER11 Top Cap: ¾ x 24 Threads tighten the Knurled ER11 Top Cap into the die body, compressing the supplied ER11 collet which properly secures the Decapping Pin or Expander Mandrel ensuring the utmost concentricity.
  • ER11 Collet: Commercially available ER11 collet to secure a variety of Decapping Pin and Expander Mandrel diameters.
  • Taper Adapter: When the Knurled ER11 Top Cap is threaded into the die body, it seats the ER11 Collet into the Taper Adapter, in turn securing the Decapping Pin or expander mandrel. The Taper Adapter sits directly above the Neck / Shoulder Sizing Bushing, allowing the Neck / Shoulder Sizing Bushing to float.
  • Neck / Shoulder Bushings: Available in many caliber specific neck diameters. Special .001” shims can be placed above the Neck / Shoulder Bushing to adjust headspace without threading the die in or out. Like traditional dies

EUFY 11S
Size: 2+8 pack
Used to replace the ones for my EUFY 11S vacuum. They fit just like the ones and got my vacuum back to cleaning really good. Didn’t realize how loud my vacuum had become until I replaced these parts.
