You guys are all correct, however I'm going to stay with my model 29 5". Auto stuffers under most conditions are extremely reliable but after teaching firearms for almost 40 years at a POST certified academy, I can tell you that they still do, in fact, have the occasional stoppage even in perfect conditions. Whether it's ammo, firearm or shooter induced is sort of irrelevant. Most folks do not practice or even know how to properly clear a stoppage and I have seen many an untrained individual make the situation worse by improper clearing methods. Revolvers can also malfunction but the biggest concern for a properly maintained wheel gun is a failure to fire. The malfunction clearing drill for that (DA) is to just pull the trigger again, which can be done with one hand. CQB with a big bruin might increase the chances for a shooter induced stoppage and it generally takes two hands (or one hand and one of something else) to clear it which may or may not be available if a big bear is sitting on your chest. There is also the fact that most folks get wrapped around the axle over big magnum velocity, which by physics increases recoil. Randy Garrett of Garrett ammo proved along time ago that a heavy for caliber, properly constructed bullet out a .44 mag at just under a 1000 fps will pass completely trough any bear alive at just about any angle. There are published papers to that effect on Garrett's website and are great reading for aspiring ballisticians. I load a hardcast 320 grain LBT or Montana Bullets at 995 fps and it's surprisingly easy on the hand and gun. It has a big meplat and I have killed numerous very large hogs with that load. Complete pass through is the norm. I teach wound ballistics for a living and have shot a lot of gelatin. I have personally shot that same load completely through two 16" blocks of 10% gel (end to end) and it kept on trucking. My wife handles and shoots that load out of her S&W Mountain Gun and is pretty fast at follow up shots. I'm not against auto loaders if that's what a person wants to carry in bear country but like anything else one needs to consider the worst case scenario.
