...JHP will expand when it hits a target (if it is going fast enough) It will go thru resistance, it just expands to do max damage to target. It will go thru sheetrock and most any other type of material you may find on the inside of a house. I once saw a guy who had been shot with a .44 mag hollowpoint and he was shot thru a refrigerator. Both he and the fridge were dead. Not much out there is going thru a brick wall if your home is brick.

Liberals are like a "Slinky". Totally useless, but somehow ya can't help but smile when you see one tumble down a flight of stairs!
