RCBS PRECISION MIC .300 WIN SHORT MAG

The Precision Mic measures from the datum point on the case shoulder to the base, giving reloaders precise readings that are in line with SAAMI tolerances. This level of accuracy is crucial for achieving consistent and safe loads, as it ensures that brass is not only properly sized, but also correctly seated.
In addition to helping reloaders ensure that their loads are safe and accurate, the Precision Mic can also help extend the life of rifle brass. By accurately measuring headspace and bullet seating depth, reloaders can adjust their reloading process to ensure that brass is not overworked and that it lasts for as many reloading cycles as possible. Determines chamber headspace and bullet seating depth to 0.001-inch. Measures from the datum point on the case shoulder to the base, giving reloaders spot-on SAAMI tolerance readings. Made in USA.
