My Desert Eagle .50AE is really mild compared to the .454 Casull or the .50 Magnum. I generally do shoot fairly hot factory loads in each, so I can tell you the rated ballistics off of the boxes.
The .50AE with 325 gr Speer Gold Dot shells have a muzzle velocity of 1400 fps, and has 1414 ft. lbs. of muzzle energy. That is fairly considerable, but is relatively weak when compared to the .454 Casull or the .50 S&W Magnum. The .454 Casull in 300 gr Hornady JXTP has a mz of 1650 and 1831 ft. lbs. of ME! Now, the .50 cartridges Hornady 440 gr Hardcast has a mv of 1650 fps, and muzzle energy of 2580 ft. lbs.! /forums/images/graemlins/cool.gif Yes, that has the energy of about one and a quarter tons!! For perspective, my 30.06 180 gr shells have a mv of 2398 fps and 2701 ft. lbs. of muzzle energy. So, the .50 Magnum has nearly the same muzzle energy of a 30.06 rifle!
In case you are wondering, a typical .45ACP round has a muzzle velocity of around 1000 fps, and delivers muzzle energy of 411 ft. lbs. So, the .50 Magnum shell has over 6 times the power of the venerable ole .45. /forums/images/graemlins/shocked.gif So, basically, even the .50AE Desert Eagle is fairly anemic when compared to the .50 Mag, and the .45ACP compares like a bb gun. And, before anyone gets upset, yes, I have a couple dozen .45 pistols. They are just way over rated in their knock down power.
Oh yeah, also for comparison, the .50 BMG rifle round has a muzzle velocity of around 2912 fps., and muzzle energy of 12,081 ft. lbs.!! /forums/images/graemlins/shocked.gif Yes, over 6 tons of muzzle energy. It is not a round for the mild person. /forums/images/graemlins/wink.gif
