I have to get it out to the range again and get the feel for it some more. I only shot some Fiocchi FMJ so far. I now have seven mags for it which is good. I will pick up some nasty HP's to try out in it and keep a couple mags full of them. I would think the low velocity and being an HP that it would fill with clothing material and not be very efficient in expanding, I'm gonna check on that.
