Bobby, I suspect you are looking for loaded ammunition, NOT BULLETS?? Am I correct?? This guess is based on your asking for something that is not corrosive, which description applies to ammo but not to bullets, eh?? If I am right, please be advised that there never has been any .357 Magnum ammo loaded with corrosive primers! So any you buy is safe in this regard. (The .357 Magnum cartridge was designed after all American ammo manufacturers had stopped using corrosive primers.)
