This video demonstrates how to use a Rockwell hardness tester to assess the heat treatment of a Mauser 98 rifle's bolt and receiver. Larry Potterfield, founder of MidwayUSA, explains the straightforward process of zeroing the machine, positioning the part, engaging the penetrator, and reading the results on the Rockwell C scale. This crucial step ensures the metal's integrity, especially after performing work on older firearms, guaranteeing the safety and reliability of replacement parts.
