[QUOTE="MagnumManiac, post: 1434768, member: 10755"] This thread is similar to what happened with a certain DG bullet design that changed ownership and was changed due to cost and ease of manufacture. It was changed from pure copper jackets/pure lead cores to guilding metal jackets to antimony added cores. The difference on game was tremendous, went from a 100% reliable text book mushroom with minimal weight loss, to a bullet that either would break up or fail to expand and tumble through the animal. I have never seen such a change before or since and do not know if it has changed back as I am sure there would have been many many complaints. Pure copper is far more malleable than any of it’s alloys and is harder to draw/swage/form without distortion on any thinner side, as we know nature likes to follow the least resistant path. Only careful heat treating at various stages helps control this. Cheers. [/QUOTE]
