So I had never heard of these, but a guy yesterday at my work was telling me about them, hydrashok bullets. He said that he shot a smaller size, about a 100lb, pig in the neck and the pressure made its eyeballs pop out. Now, I'm not gullible, and slightly still dont believe it. But the way he described the bullet was pretty neat, so I looked it up. Do you think some of you reloaders could make this round for the 450? Heres a link about the bullet.
