.429 DE ammunition is designed to enhance the famous and powerful Desert Eagle platform. Based on the famous 50 AE cartridge, the 429 DE is made with Starline brass, loaded by HSM in Montana with Sierra bullets and distributed by Magnum Research, Inc. This cartridge has a 25% velocity increase and 45% energy increase over a 44 Mag (240 -- 6" barrel). It has a velocity of 1600 FPS with 240 grain bullets and 1750 FPS with 210 grain bullets. The 429 DE features 30 degree shoulder headspaces and a neck long enough to properly hold and crimp a 240 grain bullet without set back under recoil.
I call the 429 DE Magnum the 44 Magnum Magnum or 44 Magnum2. This ammo is AWESOME! Way more powerful than the regular 44 Magnum rounds. Did I just say that regular 44 Magnum rounds Yes, I did.
Some may agree with me, that nothing compares to firing 44 Magnum in a revolver vs. the Desert Eagle. Don't get me wrong, the Desert Eagle is an awesome gun, but make no mistake, with the Desert Eagle, the energy felt from firing a 44 Magnum differs greatly when compared to firing the regular, I said it again, 44 Magnum via a revolver, due to the recoil absorption in the Desert Eagle.
But, firing the 429 DE Magnum in the Eagle definitely is comparable to the 44 Magnum being fired from a revolver. Its got a lot more punch in the Eagle for sure. The 429 DE Magnum also seems to recoil straight backwards vs. the 50ae, which seems to muzzle up and twist to the left.
That said, the 429 DE Magnum has some amazing power and seems way more controllable than its 50ae brethren. After firing a box of these puppies I did not feel warn out like I did the 50ae. I wish I brought another box to the range. Twas a lot of fun. Now for the good stuff. You probably know by now that the 429 DE Magnum is new and hard to come by - yet Sportsman's Outdoor Superstore has them for an awesome price. Thanks SOSS for makin' my day :)
