But, how much penetration can you expect with lots of expansion, low velocity and pretty low bullet weight? I don't share the current fascination with expanding bullets. Maybe they'll expand, maybe they won't. Maybe they'll penetrate, maybe not. Maybe they'll hold together, maybe fragment. Whole lot of "maybes". I load about 95% lead non-expanding bullets, and the rest are jsp's. None will expand, all will penetrate. I'm comfortable with that.
