The MiHec molds that are usually in the group buys over on Cast Boolits are pretty awesome.
I've got the 6 cavity aluminum H&G 68. Nice mold.
I shot a bunch of those at paper, gongs, etc. for years, then had a chance to shoot a couple trapped hogs at about 12'. It left me with the feeling that there's not much I'd fear in my part of the world with a Kimber full of those at 950fps.
