Where I hunt, there are big bears (and less concerning, wolves), there have been attacks within a bears roaming area of where I am at. So I always have a mag fed rifle, plus a 5 round .44 loaded with heavy cast bullets, and if stuff really hits the fan, I have a big knife always on me. A guy I know of that was from the same small town I am was killed a couple years back while elk guiding by a grizzly bear, pretty close to where we hunt. I simply won't be with just one round, and almost never hunt up there alone. I make sure my partner has a loaded gun as well, and we always talk about a plan if someone gets attacked at the onset of our hunt.
I also understand that precision ammunition should be carefully handled. At the range and while practicing, I single feed. But while hunting, if a 2nd round needs to come out of my magazine of my rifle into the chamber, there is likely a very good reason, and it's more important that it goes bang than if it gets a little scratched or dinged up getting there. The great majority of the time, the rounds I put in the magazine never get fed into the chamber, and live to be carefully placed into the chamber another day.
