404 DAKOTA

The Dakota cartridges were designed by the Late Don Allen (1941- 2003). His designs were based on the formed brass he purchased from Noburo Uno. Noburo Uno and Aubrey White of North American Shooting Systems (NASS), based in British Columbia Canada, began experimenting with the full length .404 Jeffery in the early 1980's. Allen founded Dakota Arms in 1986, initially building high end custom rifles. In 1992, Allen introduced his Dakota proprietary cartridges. Of all the magnum cartridges ever created, the Dakota line features immensely effective case capacities. All but one of the Dakota cartridges are based on the .404 Jeffery case shortened to around 2.5”. The 2.5” case length duplicates many traditional magnum length cartridges,
