LOL! I saw on Walker, Texas Ranger that if you made direct eye contact with the bear and stood your ground that the bear would acknowlege you and retreat. Anyone tried this? Dennis
A couple years ago a fellow in Eagle River, Alaska left a friend's house at 2 AM and met up with a Brown Bear. Got into a fistfight with the animal.
He won the fight. That is, he didn't spend too long in the hospital and had no permanent damage and he got a great story out of it.
My point is, it depends on the bear and a lot of luck at the time.
Conventional wisdom is that a Blackie will back off if you challenge. A Grizzly won't. So you roll up into a ball, play dead and protect the back of your neck.
So, here we have one encounter where facing down the bear and fighting him off worked on a Brown Bear where the proper choice is to play dead.

An another exception to the rule is Greg Brush's August 2009 encounter with a Brownie near Soldotna, AK. One, Greg's dog was completely unaware of the bear. Two, the bear was intent (by all evidence) on actually eating this human. Usually Brownies don't, though Black Bears will.
"It was a big boar, roughly 15 to 20 years old, but in poor body condition for this time of year. He was very thin and had significant tooth wear," said Jeff Selinger, area wildlife biologist with the Alaska Department of Fish and Game. "Very thin" is a relative term. He weighed 900 lbs and had lost enough weight that his ribs clearly showed (even below his fur) in pictures I (Lost Sheep) saw.

Every encounter is a crap shoot and no predictions can be made about any PARTICULAR encounter, though statistics
can help us better prepare.
The 480 has more mass and frontal area, the 454 has more energy. Either one will do an admirable job, but shot placement trumps EVERYTHING when the chips are down and the ballistic choices are so close together.
