The Redding 09100 Large Rifle Primer Pocket Uniformer is a dedicated case preparation tool engineered to cut Large Rifle primer pockets square to the case head and to a consistent, exact SAAMI depth specification. Featuring a precision-ground, solid tungsten carbide multi-flute cutter with an integral shoulder stop, this tool eliminates factory brass depth variations and removes bottom-of-pocket military crimp remnants. By establishing an identical seating floor across every case, it ensures consistent primer seating depth, uniform ignition, and reduced velocity spreads across shot strings. The cutting head is built on an industry-standard #8-32 male thread and includes both a knurled manual handle and a power adapter for high-volume brass processing.

Key Features

• Precision Carbide Cutter: Multi-flute, ground solid tungsten carbide head maintains sharp cutting edges and identical pocket geometry across thousands of brass cases.
• Non-Adjustable Shoulder Stop: Integral ground shoulder automatically stops cutting at the exact SAAMI Large Rifle primer depth, preventing over-cutting.
• Dual Drive Configurations: Comes equipped with a knurled Redding accessory handle for manual operation and a power adapter for motorised brass preparation.
• Universal Interface: Standard #8-32 male thread natively threads into accessory handles or power adapters and interfaces with compatible case prep centres.

Who is the Redding 09100 Large Rifle Primer Pocket Uniformer Reloading Tool for?

• Precision Rifle Handloaders — requires an exact SAAMI depth stop and the industry-standard #8-32 male threaded shank to square primer pocket floors on large rifle cases manually or on compatible case prep centres for uniform ignition.
• High-Volume Military Brass Processors — uses the included 1/4" Hex power screwdriver adapter to rapidly remove military crimp remnants and true factory primer pockets on power drivers without manual fatigue.

Less suitable for: Handloaders loading Large Pistol, Small Rifle, or Small Pistol cartridges; using this Large Rifle uniformer on Large Pistol brass cuts the pocket too deep and causes misfires, requiring a dedicated pistol primer pocket uniformer or a small primer pocket uniformer instead.
