"450 Dakota"
The 450 Dakota is one of seven Proprietary Cartridges developed by Don Allen, the founder of Dakota Arms
in Sturgis, South Dakota.
The largest of the Dakota lineup, the 450 Dakota is based from the 416 Rigby case and is almost identical to the 460
Weatherby Cartridge.  
Loaded with 400 to 500 grain projectiles this cartridge produces up to 6,770 foot pounds of energy.
