RCBS Precision Micrometer .22-250 REM

The RCBS Precision Micrometer .22-250 REM (model 88302) is a specialized reloading measurement tool designed to eliminate guesswork from precision ammunition assembly. This micrometer measures chamber headspace and bullet seating depth to 0.001-inch accuracy, delivering the level of precision required for consistent, safe reloads that maximize brass longevity and cartridge performance.

Built specifically for .22-250 REM cartridges, this tool measures from the datum point on the case shoulder to the base, providing readings that align directly with SAAMI (Sporting Arms and Ammunition Manufacturers' Institute) tolerance specifications. The 0.001-inch resolution allows reloaders to dial in seating depth within industry standard tolerances, preventing overpressure conditions and case separation. The micrometer's straightforward operation—requiring only a few twists to obtain a reading—makes it practical for both initial load development and ongoing quality control during production runs.

Reloaders working with the .22-250 Remington—whether for precision rifle competition, varmint hunting, or rifle marksmanship training—depend on verifiable headspace and seating depth measurements to ensure safe, repeatable performance. The RCBS Precision Micrometer eliminates the need for trial-and-error approaches by providing direct, quantifiable data. This is particularly valuable when working with once-fired brass or switching between rifle chambers, where chamber variations can significantly affect pressure curves and velocity consistency. Serious reloaders consider this tool essential for extending brass life and maintaining load data integrity across multiple firing cycles.

RCBS Precision Micrometers represent the industry standard for cartridge-specific measurement in hand-loading operations. The caliber-specific design ensures accurate datum point measurement for the .22-250 REM, eliminating adapter compatibility issues common with universal tools. This dedicated approach delivers higher confidence in your load data and greater consistency shot-to-shot.
