I don't believe in using a barely adequate cartridge for a close "life or death" encounter with a bear. In these cases you should be using a heavy stopping cartridge like 45/70, 444, .450, etc. Although, I don't buy into the energy figure comparison between the 357 and the 223. Many of the old buffalo guns come in with low energy figures, due to low velocity, yet anyone who has seen one at work knows most of those energy figures mean nothing and that is why the Taylor knockout values are used!! In closing : leave the 357 at home and rely on smarts in any bear encounter! (like; get the f--- outta there!)
