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]

.22 caliber cartridges[]

.22 ICL Gopher[]

Based on an improved .22 Hornet, it is similar to the K-hornet. Performance using a 40-grain (Bad rounding hereScript error: No such module "Math". g) bullet is 2,515 to 2,705 ft/s (Expression error: Unrecognized punctuation character "[". to Expression error: Unrecognized punctuation character "[". m/s).[4]

.300 ICL Grizzly' is based on the .300 H&H Magnum, and indeed the two are so similar that .300 H&H ammunition can safely be fired through a rifle chambered in .300 ICL Grizzly, as can the ammunition of another .300 H&H-based cartridge, the .300 Weatherby Magnum.[25] The casings will fireform upon discharge.[26]

.30 ICL Magnum[]
