Hmmmmm I've done this by cutting the exterior of the shell and modified our own such animal. We cut almost through the exterior of the hull down to the cup. When ya fire it the round travels as a slug and then kind of "dispersed" when it hit a harder target. Didn't know a round was designed and sold as such.....please let me know brand etc when ya get the skinny on it.....please !

My dad used to be a commercial tuna fisherman, and they did this for killing sharks. Gave pretty good range, and some serious striking power.
Seems to me Glazer Safety slugs do much the same thing.
I will check tomorrow what the brand name and model is.
