The 429 DE was designed to enhance the Desert Eagle platform. This new cartridge has a 25% velocity increase and 45% energy increase over a 44 Mag (240gr, 6-in. barrel). It has a velocity of 1600 FPS with 240 grain bullets and 1750 FPS with 210 grain bullets.

The 429 DE incorporates a 30-degree case shoulder and a long enough neck to properly hold and crimp a 240 grain bullet without recoil induced set back. Based on the now famous 50 AE cartridge, the 429 DE is made with Starline brass, and loaded by HSM in Montana with Sierra bullets.

“This new cartridge was engineered and designed specifically for the Desert Eagle Pistol, keeping in mind that the DEP is known world-wide for its awesome firepower and performance. The 429 DE propels that history into the future,” says Jim Tertin, Design and R&D for Magnum Research.

429 DE rounds are available in boxes of 20 and distributed by Magnum Research, Inc. Available options include 240 grain soft point and 210 grain hollow point.

To accompany the 429 DE cartridge, Magnum Research will soon be releasing a lineup of 429 DE 6-inch barrels in a variety of finishes. The 429 DE barrels will be compatible with any MK19 USA or Israel Desert Eagle Pistol with a wide .830-in. rail on top of the barrel and use a 50AE magazine and bolt. More soon…

Note: The 429 DE is similar to, but NOT INTERCHANGABLE WITH, the obsolete 440 COR BON, but properly engineered with a sharp 30-degree shoulder, consistent headspace, and reliable function and velocity.

  1. As a licensed small arms ammunition manufacturer, these new rounds of the 429DE are very interesting. We will be anxious to shoot this firearm and new round. Velocity is amazing.

  2. Another winner and I want one but SS does not go far. My friends have DE’s and I shot them a lot. Like the greatest revolvers ever made, the BFR’s, this one changes things again.

  3. While I’m all for new cool cartridges, there are a few super fine cartridges available that would make great additions to the platform. The 454 Casull comes to mind, as does the .460 S&W. The .500 S&W would be killer, but the rate at which you would consume ammo would put you in the poor house!

  4. Magnum research bring out a rifle version with 16 inch barrel and shoilder stock. It would make a great deer, hog and bear hunting combo.
    Also bring out the 41-429 DE and 357-429 DE in both pistol and rifle versions!
