dull broadheads, and/or poor hits. missed the brain with the .44, or she'd have dropped like a rock. Hitting brain, from inside mouth, with a 9mm,would also have dropped her. Faster repeat hit with 9mm might also have dropped her, after a first poor hit, like the .44 got. Naturally, no such repeat hit was possible with the lame assed .44, and they were LUCKY all she did was flee. No, a grizzly is NOT as fast as a horse, he just didn't have enough experience and cool headedness to be able to rationally compare the 2 animals. The grizzly IS a bit faster "out of the hole" than most horses, but top speed is about the same, at 40 mph, 60 fps.
