ICL cartridges (ICL stands for Increased Case Load) are rare hunting wildcat cartridges developed by Arnold & Vern Juenke,[2] gunsmiths who owned Saturn Gun Works in Reno, Nevada. ICL cartridges are wildcats based on conventional cases in use at the time. They feature a 45 degree shoulder[3] and the sides are straightened out compared to the parent cartridge. Most of the cartridges are considered improved cartridges since they simply create more powder space while maintaining the same caliber as the parent cartridge. 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.[4]

Quality Cartridge is the only manufacturer making new brass cases correctly headstamped for many ICL cartridges.[5]
