The .416 Ruger is .41 caliber (10.4mm), a beltless, rimless, bottlenecked cartridge designed as a joint venture by Hornady and Ruger in 2008. The cartridge is based on the .375 Ruger case which was necked up to accept a .416 in (10.6 mm) bullet. It was designed as a dangerous game cartridge particularly for use in Alaska and Africa.
The .416 Ruger duplicates the performance of the .416 Rigby and the .416 Remington Magnum. All three cartridge fire a 400 gr (26 g) bullet at 2,400 ft/s (730 m/s) generating 5,115 ft·lbf (6,935 J) of energy. However, unlike the Remington or Rigby .416s, the Ruger .416 can be chambered in a standard length action as the cartridge has a length of 2.580 in (65.5 mm). The cartridge has the same diameter of belted magnum cases but without the belt. This provides the cartridge a larger propellant capacity than a standard length magnum cartridge of the same length. The rimless design allows for the smoother feeding and extraction of the cartridge.
The .416 Ruger is chambered in the bolt-action Ruger M77 Alaskan and the single-shot No. 1 Tropical rifles. No other manufacturer currently chambers this cartridge. Ammunition is available from Hornady, who is the sole supplier of ammunition for the cartridge.
