Magnum Research has developed the 429 DE (Desert Eagle), a new .44 caliber pistol cartridge engineered to enhance the Desert Eagle platform. This cartridge delivers a 25% velocity increase and 45% energy increase over 44 Mag (240 grain from a 6″ barrel). Based on the 50 AE cartridge design, the 429 DE is manufactured with Starline brass and loaded by HSM in Montana with Sierra bullets.
The round features a 240-grain jacketed hollow point bullet designed for stopping power and reliable performance. Each box contains 20 rounds of brass-cased ammunition that feeds smoothly and maintains consistent accuracy. The 429 DE caliber is specifically designed to maximize the capabilities of your Desert Eagle firearm.
