Oops. I overlooked twist rate. And I was going to get rich selling wadwilly bullets. But I have another idea more suited for bear loads. I will cast super hard(like a preacher's ding-a-ling). Then I will place them standing up in cold water. Next I will heat the front end with a torch to alter hardness. The result will be a bullet hard on one end and soft on the other. The very hard rear section will assure extreme penetration of the soft and expanded front section. I forgot to state that this will be a gas check design. I will produce 1000 of these and send them to the big dude in Rhode Island with the Walker hound in his avatar. Everybody else will have to pay $75 per 1000 delivered. I might call this version the superwilly.
