I would be interested in some data regarding bullet nose shape and penetration and jacketed/lead bullet design and penetration/fragmentation. My opinon on using a handgun cartridge for hunting is that it is mainly a loud arrow for most intents and purposes. I've shot a couple of middling sized black bears with a .357 mag loaded with 168 gr hardcast semi-wadcutters and it was interesting seeing what the bullet(s) did. I also have shot a fair number of deer with various .357 loads to come up with this opinion. I haven't had the opportunity to shoot a hog with a pistol, when I've had the chance the rancher wanted them dead any way possible and would not put up with "goofing off" with a pistol. I carry a .454 Casull loaded with the 325 gr Buffalo Bore load as a second gun when I'm in Alaska. Recoil is hellacious but I figure if it comes to using it, I'm in contact distance. I do practice with these loads a bit, much more so with the 260 gr Magtech loads as well as the Winchesters in 250 and 300 grs. I would definitely like to find a bullet that will give deep penetration with a little less velocity than the BB loads; I see no need to unnecessarily beat myself up if it can be helped.
