Forgive me Graybeard.
Never ever been charged by anything including a bear. However....Went to NW Montana after black bear with my .54 hawken and round ball. Outfitter carried a 460 roland, but he guided the two bow hunters. His wife was my guide...from experience of walking up the mountain....I had no chance of outrunning her. SO, his advice to me. If a Grizzly decides to charge you. Stand very still, roll the hammer back and when it gets there, do your best to shove it down its throat and pull the trigger (not the set trigger), then relax, cause you are gonna feel like a semi hit ya...cause it did. Now the real question: Have shot a lot of 44 mag and 357 over a number of years....As many have said, the 357 can handle most game (Whitetail and smaller) under the right conditions. The 44 can handle the same with more authority (yes the 41 to). Have yet to meet the man than can get off 6 quick shots with full .44 mag load. Not to say someone can't, I just ain't seen it.
Now thats my bear story and I am sticking to it....come to think of it, I am sticking to the chair too...time to go
