Regarding the SWC, I think Elmer Keith was years ahead of his time with that bullet design. I'm suprised some of the larger ammo manufacturers havent come out with an 45 ACP H&G 68 factory load, making 185 PF, with heavy taper crimp. It'll feed in most (taper crimp is key) 1911's and do it all: Defense, hunting and target shooting.
In .357, I wouldnt feel undergunned with the average 158 SWC, but it is a little heavy on the penetration. That being said, how much more penetration does it have than a JHP? A shooting that I have quite a bit if interest in featured a .357 mag 158 gn jhp bullet hitting the suspect in the kidney area, passing through side to side, and exiting, and the bullet wasnt recovered. Suspect dropped momentarily, then got up and continued running. How much worse would the SWC have performed? And maybe, since it has good penetration, the velocity doesnt have to be quite so high then? Then its not quite so painfully loud for shooting indoors, etc. So maybe a 158 SWC at 1100 fps? About 173 PF?
