CMJ Bullets are fully coated in pure copper. The core consists of lead antimony and the CMJ design allows for zero jacket and core separation. The majority of our CMJ Bullets are restruck resulting in increased consistency and overall accuracy. Restriking is the process of forcing the already plated bullet into a shaping die and ensuring the form of the bullet is exactly in line with the design. Thus, no production markings or deformities will remain. Also, restriking ensures that each bullet is precisely the same as the one before. .355 Diameter 147GR Round Nose Profile CMJ 9MM 500 COUNT
