I had a couple molds modified for optional HP configuration. Just google "mold hollow point service". They will modify your mold if you have one you like. It has been a while so I have forgotten who I used but they performed well as far as casting. Have not tested on flesh. I usually WD but with HP I did straight air dropped WW. It will be hard to beat the performance of the experienced guys here selling their proven alloys and configurations - depends on how much you want to cast your own. Other hot topics on here point out the possible inconsistency with Cast performance and I have witnessed some long chases myself using well placed cast but we old guys have not forgotten when jacketed bullets were not very good either. Cast can be sized to fit better if it is needed but real good jacketed bullets now give me the performance I need for hunting. I only say this as to why I don't cast as much anymore. Good luck.
