The RCBS Precision Micrometer for .22-250 Remington is a dedicated headspace and seating depth gauge designed for reloaders who demand chamber-safe, consistent ammunition. If you're loading for this classic varmint cartridge and want to dial in your loads with precision, this micrometer measures critical dimensions down to 0.001 inch—the kind of accuracy that separates safe, predictable rounds from guesswork. It reads from the datum point on the case shoulder to the base, giving you SAAMI tolerance confirmation and the confidence that your brass will live a long service life.
Reloaders working up loads for .22-250 rifle chamber specs need a tool that speaks directly to their gun's actual dimensions. Generic load data gets you close, but chamber headspace and bullet seating depth vary from rifle to rifle. This Precision Mic bridges that gap with straightforward mechanical measurement—no batteries, no calibration required—and helps you avoid the common traps that shorten brass life or, worse, create pressure problems. Whether you're developing a new hunting load or maintaining your brass inventory, this gauge is the kind of tactical detail that serious reloaders refuse to skip.
Built to RCBS standards, this tool earns its spot on the reloading bench as a core safety device. Once you establish your chamber's true headspace and confirm bullet seating depth, you can reload with the precision and repeatability that turns a good rifle into a reliable one. For .22-250 shooters—whether you're chasing varmints or testing handloads at the range—this micrometer is a straight-talking investment in accuracy and brass longevity.

| Measurement Increments | 0.001 inch |
| Measurement Range | From datum point on case shoulder to base |
| Brand | RCBS |
The RCBS Precision Micrometer measures two critical dimensions: chamber headspace (from the datum point on the case shoulder to the base) and bullet seating depth. These measurements confirm that your finished cartridge fits your specific rifle chamber and that bullet depth is within SAAMI tolerance—essential for safe pressures and consistent performance across multiple shots and reloads.
Yes, this micrometer is designed specifically for .22-250 Remington. It is calibrated to that cartridge's chamber specifications and datum points, so it is not interchangeable with other calibers.
By measuring and confirming headspace and seating depth to 0.001-inch accuracy, you ensure your reloads fit your chamber safely and don't force into the chamber (which stretches brass prematurely). Consistent, chamber-safe loads mean less stress on the case walls, fewer resizing cycles needed, and longer service life from your brass.
