I'm new to reloading, and I'm looking into loading .44mag for use in a desert eagle... Jacket 45 Cal slugs are cheap enough to obtain but can they be swagged to .429 safely from .45? If so do I use regular load data from there or are their any specific things to take into account. I'd just cast some good ole lead like for my .38, but with the deagles gas system that's not an option, and I don't wanna risk damaging a $1200+ gun with powder coated boolits. Anyone here have experience with this or even desert eagles specifically?
I am and have been under the supervision of a veteran reloader that has taught me a great deal and I ran this idea by him and isn't sure what to think, he recommended just ordering jacketed .429 projectiles.
