ORIGINAL: Hillwilliam If your background is metallurgy, we might have some fun convo's. That seems unlikely, if earlier posts to this thread are typical of your approach to discussions. Again, Steel bullets are not what you want for civilian use. The military uses them in some cases for armor piercing rounds but they have to be coated in order to not damage the rifling. My post on 4/8/2012 at 11:05:24 AM addressed that, have you read it for content? Bismuth would be a good compromise as it's already used in fishing tackle. My post on 4/8/2012 at 11:27:38 PM proposed Bismuth as a compromise metal. Owing to bismuth's crystalline nature, the bismuth bullets shatter into a non-toxic powder on impact, making recovery and recycling easy. The lack of malleability does, however, make bismuth unsuitable for use in expanding hunting bullets. Bi-Ni alloys with limited ductility date back 60 years, and some metglas powder metallurgy might improve on that, even to the point of pressing into copper shells, which is the way many modern bullets are made. Anyway, that last might illustrate the difference between a creative, constructive, knowledgeable approach to such topics, and various sorts of accusatory personal assertions, pretensions to expertise, etc. And that doesn't even begin to address how ductile-iron, steel-composite, etc bullets could be engineered by geometry or materials to deform instead of penetrate when striking hard or soft targets. I'm not particularly interested in further convo about the matter. There's easily enough sprouts there for a half-dozen patents. Maybe have a read and a think before you rant ad-hominem next time ... ...
