The Redding 6.5 Creedmoor Small Base Die Set (MPN 48446) is a precision 2-die reloading set engineered to restore fired brass slightly below standard SAAMI minimum dimensions. Designed specifically for the 6.5mm Creedmoor cartridge (.264" bullet diameter), this mechanical reloading tool ensures reliable chambering and cycling in firearms with tight clearances. Both dies are machined from heat-treated alloy steel on precision lathes, hand-polished, and ultrasonically cleaned, mounting to standard reloading presses via an industry-standard 7/8"-14 thread interface.

Key Features:

• Small Base Resizing: Sizes the case base diameter and shoulder back slightly beyond standard full-length dies to prevent cycling stoppages in tight chambers.
• 2-Die Configuration: Includes a full-length small base sizing die with an integrated decapping rod and expander button, paired with a standard bullet seating die featuring a built-in crimp ring.
• Precision Machined Construction: Crafted from heat-treated alloy steel for tight dimensional tolerances and wear resistance during high-volume case reforming.
• Multipurpose Storage Box: Ships in a dedicated Redding die box that doubles as a cartridge loading block and contains a spare decapping pin.
• Universal Press Mounting: Uses standard 7/8"-14 threads compatible with single-stage and progressive reloading presses.

Who is the Redding 6.5 Creedmoor Small Base Die Set for?

• Semi-Automatic Rifle Handloaders — Requires full-length resizing below SAAMI minimum body dimensions to ensure smooth chambering and cycling of 6.5mm Creedmoor ammunition in AR-10 and semi-automatic modern sporting platforms using a standard 7/8"-14 thread press.
• Precision Match Shooters with Custom Chambers — Delivers complete body and shoulder reduction across a 2-die set to guarantee reliable clearance in precision bolt-action rifles built with tight-tolerance or minimum-spec match chambers.

Less suitable for: Handloaders running standard-specification factory bolt-action chambers who want to maximize brass longevity, where a standard full-length or neck sizing die set prevents overworking the brass; or extreme long-range competitors requiring micro-adjustable seating and bushing neck control, who are better served by a bushing neck-sizing die set or micrometer-adjustable competition die set.
