Great.
Wuchak is right, I never give out load data on line but I'll tell you where to get it. My 14yr. old son just started hunting Whitetail with his .357 blackhawk and when I started developeing his load, I went to the 180gr. XTP. after some penetration testing, I found this bullet to be good. Then I tried the 200gr. WFNGC from Cast Performance and this bullet would penetrate just as deep as my 310gr. FN from Oregon Trail out of my .44mag. You give up some penetration with the XTP because of expansion. People say that a .357mag. is marginal for deer, mostly because of lack of penetration. ie. "only close broadside shots" ect. This bullet will penetrate the largest deer from quartering and break bone to get to the vitals. Try it and you will not be disipointed. Cast performance will give you the data for their stuff and Hodgdon will as well.
Good luck and let us know how you do, Tim.
