The Redding #24 Bullet Seating Micrometer (MPN: 09084) is a mechanical drop-in upgrade designed to replace the standard seating plug in compatible standard Redding bottleneck seating dies. Machined with a 1/2"-20 TPI interface thread, this precision tool gives handloaders direct-reading depth adjustments calibrated in clear 0.001-inch increments. It allows users to make exact, repeatable adjustments to Cartridge Overall Length (COAL) and bullet-to-lands jump without resetting die lock rings or relying on trial-and-error measurement.

Key Features

• Direct 0.001" Graduations: Laser-etched micrometer markings allow bullet seating depth adjustments in exact 0.001-inch increments.
• Drop-In Die Conversion: Replaces standard knurled seating plugs via a direct 1/2"-20 TPI thread fitment.
• #24 Stem Profile: Contoured for standard tangent and secant ogives across select short-to-medium .224-calibre centrefire cartridges.
• Pure Mechanical Operation: Requires no electrical supply or batteries, functioning entirely via precision mechanical threading for reloading bench use.

Who is the Redding #24 Bullet Seating Micrometer - 222, 22 Ppc for?

• Benchrest Precision Target Handloaders — Adjusts Cartridge Overall Length in direct 0.001-inch increments on standard 1/2"-20 TPI dies, allowing target shooters to precisely tune bullet-to-lands jump when handloading .22 PPC competition rifles.
• Varmint Hunters Handloading .222 Remington — Delivers exact bullet seating micrometer adjustments in 0.001-inch increments for the #24 stem group without altering the primary die lock-ring settings between different varmint bullet profiles.
