Bob,

If you search on youtube using "Grizzly charge" you should find it. I can't try it out here at work due to massive firewalls and filters, but I saw it there last night at home.

Its pretty disturbing. I could only hope I'd have the presence of mind to fire off a round.

Thank goodness the bear's reaction to the gun was so sudden and quick. I would have thought just inertia would have brought the two into contact. Sheesh!
