I know, personally, at least four people who've fupped duck their Desert Eagles using cast bullets. Even though the manuals say NOT TO USE LEAD BULLETS, THEY DID SO, ANYWAY. Thus causing them to fork out basically the whole cost of a new DE to get it repaired. People can be really stupid at times, can you follow THAT logic?
You can't do a blowback semi-auto in .357, as the bolt would have to weigh five pounds to be safe enough to operate the thing without it unlocking too damn soon, and blowing out the case head.
But if you can't see the logic there, there ain't no hope for ya. You'll also note that Ruger's already discontinued the Deerfield, ringing any bells yet? Ruger repaired a lot of them with lead-soldered actions, too.
Lots of Glocks go kaboom when overused with lead bullets, too, polygonal rifling and cast bullets don't go well together. H&K doesn't recommend cast bullets in the MP-5, either.
