The RCBS Precision Mic determines your chamber headspace and bullet seating depth to 0.001 of an inch, giving you the precision needed for safe, consistent handloads. The precision micrometer measures from the datum point on the case’s shoulder to the base, giving you spot-on ANSI/SAAMI tolerance readings.
This specialized 308 Winchester seating die is an invaluable tool for handloaders who want to achieve safe, accurate loads that will extend the life of rifle brass. Its measurements from the datum point ensure precise readings in line with SAAMI tolerances, which is crucial for achieving consistent and safe loads and ensuring brass is not only properly sized, but also correctly seated. By accurately measuring headspace and bullet seating depth, you can ensure brass is not overworked and lasts for as many reloading cycles as possible.
