429 DE Magnum Ammunition for Sale

Introduced in 2018 by Magnum Research, the .429 Desert Eagle Magnum harnesses a rebated, bottleneck case necked down from the .50 Action Express to accept .429-inch bullets originally used in the .44 Magnum. Factory Glacier Ridge jacketed hollow point loads propel a 210-grain projectile at 1,750 fps for 1,427 ft-lbs and a 240-grain soft point at 1,625 fps for 1,407 ft-lbs of energy. With a SAAMI maximum pressure of 46,000 psi, these cartridges deliver deep penetration and controlled expansion—ideal for medium-game hunting or bear-defense in a Desert Eagle Mark XIX. At Sportsman’s Outdoor Superstore, you can find .429 DE Magnum ammo in both hollow point and soft-point configurations, compare velocity ratings and bullet profiles, and purchase your rounds today with competitive pricing, secure checkout and fast shipping.
