Yup--I know exactly what you mean. I'd trust my cast HP's over factory jacketed any day. This is my .40S&W fired into shredded newsprint "mush" (my technical name for a jug full of water-soaked newspaper, similar to a wet-pack).
I don't remember the specifics on penetration depth, but Gold Dot and Hydro-Shok didn't expand for schtick compared to these...
