There is a couple of copper babbits that you can mix in your alloy to give just a tiny bit of copper to toughen up the bullet too(I used about .5%), for good penetration while still being soft for the good mushrooming. I've tested a little bit of it with my 9mm. I had the bullets doing good for holding its mass while mushrooming nicely. I shoot into a wax block, which acts a little like water ,so it is harder on bullets than tissue, so a good performing bullet in tissue may have to be "over expanding" a little in the wax. Haven't been able to test that theory yet.
