I'm not a big fan of the Keith 170. I have always had best luck using JHP's when hunting with the .357. I have never found the .357 wanting for penetration when using 140gr or heavier bullets, but I have found it wanting for frontal diameter when animals get larger. So for me, the .357 benefitted greatly from JHP's. I have always been happy with the performance of a quality 158 JHP.

I guess I'd want a heavy cast bullet if I were trying to take down a moose, but then I wouldn't be picking a .357 for that particular job.
