CCI Large Pistol Primers #300

CCI Ammunition manufactures CCI Large Pistol Primers as high-quality ignition components that deliver reliable, consistent performance across a wide range of handgun cartridges. Reloaders trust these primers for their durability, clean ignition, and dependable function in both standard and higher-performance loads.

Design and Construction of  CCI Pistol Primers Large

CCI engineers its large pistol primers with precision to ensure uniform ignition and safe operation. Each primer consists of a carefully formed metal cup, an internal anvil, and a non-corrosive priming compound. The company is known for using slightly harder primer cups compared to some competitors, which helps reduce the risk of accidental ignition during handling and feeding—especially in progressive reloading equipment.
