Deagles only come in 50ae!
"Deagle" is a word that shouldn't be seen in an adult, non-gaming forum!
Deagol found the One Ring in the river Anduin, and was murdered by Sméagol, who wanted it for his
precious, his birthday present.
Gollum,... Gollum....:rolleyes:
AA#9 works, so does 2400, W 296, and H110. I have used AA#9 and 2400 in my Desert Eagle, and I use magnum primers. Faster powders can work, but you will need to CAREFULLY experiment to find a reliable load.
Don't shoot lead bullets, I won't shoot plated, either. Don't go heavier than 240gr (there's no need, and IMO, no point) or expect issues.
Don't "cup & saucer" the gun. In my experience, the magazine needs to "float" or feeding problems will happen.
There are several old threads in TFL that discuss the DE, its habits, and feeding requirements. The information you seek is here, just search a bit.
The Desert Eagle is NOT a handgun like other handguns, it needs its own diet, and type of "exercise" (how it is shot). Don't expect it to thrive or fly well on anything else. I got a .357 in 1984, and a .44 in 1990. I don't have any of the new production guns, but I would not expect them to behave much, if any differently.
