.330 Dakota

The .330 Dakota is in the proprietary cartridge class and was designed by Don Allen. Proprietary rounds are trademarked by private individuals or corporations, and the cartridges are harder to find on the commercial market. The ballistic performances based off two .330 Dakota rounds for velocity are 3,200 ft/s (210 gr) and 2,950 ft/s (250 gr) The high cost of brass for making hand loading cartridges usually turns shooters off from buying Dakota rounds. Factory ammunition is also harder to find than regular commercial market brands. The cases are able to hold a large capacity of powder. The .330 Dakota uses .338 diameter bullets and is based off the .404 Jeffery design. The casing is narrowed down at the neck and shortened from the original .404 and has the belt removed. The .330 Dakota is said to produce 10% more energy than the .338 Magnum.
