ICL cartridges

Most of the line of cartridges carries an animal name in addition to a numeric designation. It is one of the most complete lines of wildcats, having a large number of cartridges with a variety of calibers. Quality Cartridge is the only manufacturer making new brass cases correctly headstamped for many ICL cartridges.
