Built with the goal of achieving .300 Weatherby ballistics or better combined with the accuracy of the .300 Win Mag. Uses an 8mm Remington Magnum case with a 35 degree shoulder. At 250 yards, .300 Jarrett with a 200g bullet has more energy than a .338 Win Mag with a 250g bullet. Gets the job done with authority on most African animals. Our number one seller!

The cartridge that we have the most experience with. Very versatile. A major influence on our rifle build history, with its creator, P.O. Ackley, being a major influence of Mr. Jarrett’s work. Three main features that make the .280 Imp. great: first, factory ammo can be used in the Improved chamber, second, brass life is good, and third, versatility created by a high degree of accuracy across the 120g to 160g range. Excellent for a wide range of animals.
